i want to make healer class but everytime i party (as dps) i always see the healer doing CS then help dpsing not once not twice, like everytime iam in party.

Is this requirement? Do i get booted if iam not doing this? At first i though a low level dungeon thus the healer help but, even in high dungeon like antiower the healer still doing it and he's doing it quite frquently yet still healing everyone at the same time.

I have almost zero experience as healer in mmo, i want to try in this game because how easy to switch class in here but the though of doing that just..... My eyes will be busy looking at the party hp (and some aoe dodging i guess) and i still need to stance dancing and help dpsing?

Anyone can help with some insight?
Not sure if server affect people playstyle but i play in tonberry (jp server)
