I agree with
@Silosobi that the R2 pets base dps should increase significantly.
Regarding the timed proc, I was thinking about something like this for a while. I don't think the warders should act on their own, I think it should be something the pet does to help the master out. Then I started thinking about how that could be done and not be OP. First thing that comes to mind is Kick. Our kick skills are pretty much 100% useless until we get good procing boots, then those boots become the only source of viable damage output from kick. I don't think i've seen a kick land for more than 30 even now.
What if, on this timer be it 30 seconds or 48, etc. The pet gives the master an emote that they have latched on to the Target, pinning them down to the ground and opening them up to attack.. In this 1-3 second time, if a kick is used, it will do a large amount of damage (500ish non crit?) and will be guaranteed to land. If completely successfully the warder could get some kind of bonus, like a reward for helping me out. Maybe they could get a temporary attack buff that boosts their dps or accuracy significantly?
If we need balance for this, if the kick is not successfully performed by the master for whatever reason, the pet can be thrown off the target and take some damage (queue the knockback animation =D), 1-2k? I personally don't think that's necessary but Devs like their options =P
I think this would further bridge the lore dynamic between pets and their owners. I would actually like to see this on all bst pets scaled through the levels, but i'm not sure how or if that could be done.
