Let us have at least 1 stun
I agree with those who have said "Leave knockdown alone"
There is no reason to remove it.
It is the last fun skill that a guardian has.
If you feel you must remove it, please give us an AEO stun skill in its place. (like champs and hunters have)
To make redline guardian DPS viable for soloing in Mordor, remember that the morale of the mobs is from about 60k up to 170k,
so taking 3 minutes to kill each individual mob is tedious. (plus the respawn time in some areas is very fast)
Also bear in mind that until you hit L112 (when you get access to the first available LoE gear bartered for ash),
it is very difficult to equip more phys mastery as well as LoE and finesse.
So people posting DPS data who have hit Level 115, and have massive phys masteries are NOT giving a realistic picture of what it's like to solo in Mordor at Level 105-112.
My own guardian is at L 107 and has a phys mastery of only 50k.
I could increase it, but at the cost of much finesse, morale or LoE.
Having said all this you are on the right track:
1. Increase damage of base skills dramatically.
I haven't played on Bullroarer but from the stats already posted, I can see they need Much more boosting yet.
2. Eliminate a 10 tier bleed system, and replace with much simpler, faster system.
Congratulations to SSG for boosting the Red Guardian.
I have been asking for this for a long time, and it fell deaf on Turbine's ears.
