Would it be viable to redesign creeps class traits to be changed to prevent a cookie cutter build? I play a r12 warg and here's my thoughts.

Traits to remove and make rank gated passives for a warg.

Armour Boost. Make passive to redesign class traits that focus on enhanced skills.
Long Strides. Only the warg race can use the stalker class increase the racial trait and remove the class trait.
Enhanced Stealth. Speed boosts should be racial remove and introduce Enhanced Shadow Stance.
Resist Boost. Make passive to redesign class traits that focus on enhanced skills.

Discuss,
Physical Damage Trait(passive). Personally I like the simplicity of having only a tactical damage trait even when freeps stack tactical mits. Before it was shadow mit, fire mit, and later acid mit class specific now its just tactical mit. Creeps need to compensate for at least a 2nd damage type so freeps don't effectively stack mits for only 1 type. I'd rather see it freeing up a class trait slot and make it a passive that can be changed between physical/tactical. Most of this wouldn't work i.e. spiders doing ancient dwarf damage but if a new name was created like blahblah damage type it could be plausible for a spider to deal physical damage instead of tactical.

Change current and add new traits for a warg.
///////////////////////////////////////////////////

1 Enhanced Sprint 2. -480s sprint cd setting your run speed to 133% for 20s. Only one sprint class trait can be usable at a time.

2 Enhanced Rallying Howl. Make the rallying howl a less effective skill usable without the trait. The enhanced trait enhances the skill dramatically.

3 Enhanced Sense Prey. Change it from a regular track skill to a 10-20s buff on a 1min cd that increases your stealth detection dramatically. Usable in stealth, while moving, and in combat. Does not affect burgs hips buff. I feel the stealth track range is so low the warg may benefit more from a 20s buff that increases stealth detection if it's value is high enough. May be unwise to give up current tracking method. Give the skill the option to stealth track normally, an enhanced sense prey 2 trait.

4 Enhanced Rabid Bite. Turns this skill into a buff as you foam at the mouth. For 10s your next 3 attack skills deal damage to targets power pool.

5 Enhanced Disappear/Topple. -300s disappear/topple cd. I can dream.

6 Enhanced Shadow Ideas: multiple examples
-% to attack skills cd, +% to positional damage, increased crit from stealth chance, decreased miss from stealth chance, + stealth lvl, +% to debuff durations done by you. Enemies tracking range on you is decreased to 90m.

7 Element of Surprise. If no enhanced shadow stance class trait that increases crit chance from stealth than element of surprise has a 100% chance to crit from stealth. If yes on enhanced shadow stance crit from stealth than change element of surprise to 20% chance to crit from stealth and +3% to crit on attacks while not in stealth. May even be able to get rid of element of surprise trait.

8 Enhanced Howler (flayer) Ideas: multiple examples
-% to attack skills cd, +% to brute chance, +% to bubble's size, increased crit rating, + stealth detection, +% to debuff durations done by you.

9 Enhanced Eye Rake. Change to -% cd if enhanced shadow stance -% attack skill cd idea is used. Also add a +% to eye rake debuff duration.

10 Enhanced Snap. Critical hit no longer needed to silence or disarm target depending which stance used.

11 Enhanced Pounce. Turns pounce into into an immediate skill.

12 Enhanced Scratch and Snip. Turns this skill into Scratch, Snip, and Bite. An attack skill that does three hits. The 3rd hit deals slightly more damage than the first two attacks.

13 Damage Mod. Only one can be used at a time. This is only if it won't be made passive.

Many different skills to enhance in many different ways that can/should be used to complement each other catering to a variety of play styles and types. The suggestion would be to not limit the amount of passives or skills usable by not slotting class traits but enhancing the class' skills to complement certain ways to play making the warg really good in one area and less in another. Some of what I listed are too op like enhanced rabid bite and enhanced sns would drain a burgs power pool really quick but just some ideas to work with.

The enhanced stance traits should offer bonuses to trait but not be a necessity in order to use the stance not being traited for even though you can trait for both.

At this point it is probably too late for u6 or u7 unless it's already being worked on but, maybe it's not too late to suggest for RoR. Also creeps would like a legendary trait to further tweak a class to have multiple ways to play.
