easy?
Q: tank or easy?
Please do try the group tank with CP 200 ~ 300 DPS & healer
Q: healer is the easiest, is not it?
I think that it is okay to say so if GDPS can support even a group with less than 10,000 even though there should be two tanks and DPS that do not taunt
Q: DPS is the easiest thing
Because there are multiple man, they can only blame others. getting low DPS or poor movement?
Conclusion
Whatever profession is, it will become difficult or easy in the end depending on the friends who play with them.
