Hi Orion, I've been giving "Bastion of Light" and the other skills/effects associated w/ it some thought. I feel that making it a hot spot will not be good ideas because some of the raid/instance and delving mechanics will basically negate these skills/effect. For example:
1. Puddles = will have to be constantly moving out of them and therefore rendering the hot spot useless along w/ all the other skills/effect associated w/ Bastion of Light.
2. Eyes (and the associated effective) = will force the guard to move. A good example of this is Sagroth and the yellow eye someone in the group, including the tank, get.
3. Punts = will move the guard out of the hot spot rendering "Bastion of Light and the associated skills/effect less effective or useless.
4. Kiting = will render Bastion of light and associated skills/effects completely useless.
I think a better solution would be an AURA around the guard w/ the same effects. Please reconsider the HOT SPOT idea. Thank You
If the description of the skill and its trait specifies a radius, then 30 meters is a huge zone (War-chant radius with the talent is 20 meters) which is unlikely to have the problems you described, rather the opposite, it will be difficult to use such a skill because of the effects of control. If it's a diameter, it's still a pretty wide area, and given the not too long recovery time of the skill it can always be used quickly in a new position. The game is full of positional skills like banner and tar, and they don't cause much of a problem for gameplay.
