im sure this will be implemented along with many other things in thier "free 2 play, pay 2 win" model we all know will happen. A super massive server in the first place would have solved this problem
why dont you just make 1 super massive server for each region (ie: 1 east coast, 1 west coast)? I understand it will have to be instanced. But it would eliminate the need for cross server.
just get rid of servers. have only 1 sever. no set factions. have the choice to align yourself with reps/imps/neutral. global market with statistics. create player owned/capureable areas for pvp and have that unlock instances and/or buffs for owning faction.
sounds like you are just crap at your class. their heals are amazing when used right. healing needs a stacking nerf just like dot and debuff have. you don't need a boost. just l2p
