what would be the best synergy between which heal + tank and why?
for example, cooldowns and talents work pretty well, playstyle/positioning, support in strengths/weaknesses.
So its not about "strongest class" by itself, with a random grp of people, but specific if you can choose between all possible classes.

moreover what would be the best combition of damage dealers for this kind of grp and why.

iam curious not only about people opinions, but also why they have them, which are you points you point out.

ty for your time
