hey all 2 friends and me are thinking about play again for a while. not serious raiding, but have lot of questions. 1) do i need to buy the 3 or 4 expansions that arent f2p??? i thought only the last expansion wasnt f2p. and if thats true. do u need to buy all them, or buying last one get every exp before that too? 2) mercenarys. are they for every char or for all the account? i mean can i get a mercenary and use it on every char?. wich mercenary is good as f2p? i think healers are better but wich one. 3) wich clases should avoid? i had a brigand and bruiser 90. but i have read bruisers are useless and brigand dont do dmg and his debuffs are pretty useless now. rangers are prety bad right now i read. 4) how dungeon finder works? is active? or noone uses it. 5) if i buy the cheap aerakyn. could i upgrade it to a better version after? or must be done before creating the char? 6) the new channeler is good? i mean do some dmg or is a full healer only? cant find lor of info we stoped playing at around lvl 90 on sentinel fate i think. and was thinking about make a new char an see everything again we 3 and mercenarys. could we do every group content and even some raids like that?
