1.Wizard, Pyro, Linker, Thaum 2, Alchemist (linker mobbing and poison/electric buffs through attributes, large damage buffs from thaum as well as swell body exp, access to valuable alchemist perks, early game DPS)
2.Wizard, Cryo, Linker, Ele 3 (main DPS, CC, links and linker damage attribute buffs, lots of sustained AoE damage)
3.Swordsman, Pelt, Barb 2, Squire 2 (swashbuckler for leveling/mobbing, high physical DPS after pelt with barb, useful squire abilities)
4.Cleric, Kirvis, Priest 2, Pardoner 2 (healing, early game dps, very useful buffs (blessing for multi-hit skills, sacrament for archer, swordie and thaum, useful pardoner abilities)
5.Archer 2, Sapper 2, Wugushi 2 (very useful for flying mobs with 2H bow attribute, single target DPS and fast bossing with Wugushi, high AoE with broom trap and throw gu pot)
I think this would be a very strong 5 man comp for team play. It represents each class, it allows you to have the merchant classes in your team for personal access and making profit. It has tons of DPS, mobbing ability, AoE, bossing capability, healing, buffing, leveling speed, etc. and it’s pretty general in its use. The Squire can eventually go templar as well.
If you stick with this 5-man, you’ll be able to have access to gem roasting, free repairs, guilds, skill scrolls and high-duration buffs, item awakening and you’ll be strong in PvE. With these main characters established, you can go ahead and level alts afterwards.
