Also, IMO druid/warden build is not the same as any other druid build, We don't have much HoTs. Instead, D/wd build is similar to P/k. Survivability and instant group heals. With mdamage buffs, our group heals can crit more than D/S ' group heal and D/wd have 4group heals--well 5 if you count briar shield!!! that is the reason why I went D/WD/S in the first place so if cleanse is needed I can temporarily go as a D/S and do the job, otherwise D/wd has amazing heals.
Your m.dam buff does not affect your group heal crits. M.dam affects hots and healing bonus...you're thinking of
this (which doesn't affect crit btw, it gives you healing bonus).
D/Wd Group Heals:
One
Two (more of a 1/2 imho) - a 3 target heal with no predictable target apart from on one person is not a 'group heal' that I'd call dependable.
Three (not really a group heal, more a group regen that lasts for 40secs if you stand in one spot)
Four (yes I'd count Briar Heal as a group heal, tho again it isn't a predictable casting of a heal, more of a cast the buff on someone and hope that the person you've cast the buff on will trigger the heal onto the group when they get attacked i.e. stand within 70 range of the person with the buff and hope for the best).
Five (Gift Pulse - super nice)
Yes I personally think D/Wd is great as well.
Oh and Collisto, one thing I'd readily admit is that I hate to agree with Raves over anything (just for the heck of it), however when it comes to druid healing, a little less ego and a little more enthusiasm (or at the very least a little less childishness of 'ooo everyone hates you') in learning from someone who's been playing the class endgame and knows the class back to front will help you a lot.
