Its balanced, archers got archery Will that gives extra range and counters trigger that give a bit boost c dash for he counter rapid for elfs and counter power for d efl only affecting skills , archers --> mages (in my opinión because range, on good jewells ofc) Mages get some new skills here, vortex slug, arcane shield that absord most part of the damage as mp, and also get chances to enchant some skills like arcane power,passives,etc.. so they Will hit stronger than normal interlude.
Daggers got potential abillity, and get also counters (almost on beta they did) so they Will be hitting very hard criticals.
But at the end, on l2 its all about support and good hands...so..
