Technically gear/ skills heavily outweighs team comp.
There was a meta back then ,
2 smns, 2 blm , mix of both etc
Then ppl wanted nerf
Cuz double smn was to good
Double swiftcast raises + disease
( slowing target's movement too)
So SE implemented the 1 melee & 1 ranged dps rule.
Double blm was also rediculous because of the non stop sleeping aoes.
So SE changed up the sleep and added dim returns & resistance.
But imo i think a meta will be viable in frontlines as we will get to double roles thus allowing to go in a same role
I.e 2 ranged = 2 smn
2 melee = 2 drgn
2 tanks = 2 mrds
2 healers = 2 sch or 2 whm
Or both
Imo having 2 smns & 2 schs would be so broken cuz there will be 4 more "party members" on the team.
Both teams do 2 smns & 2 schs
It'll just end up as modern pet warfare 4.
SE will probably fix it if ppl find it cheap.
