I play in a 5 person group and we are level 13 going on 14. Presently we have a hybrid defender/leader, a hybrid defender/striker, 2x pure strikers, and a pure controller. We have only played a few games with this group dynamic as one of our pure strikers used to be a pure defender but he got bored. Does anyone know what the ideal ratio of defenders, leaders, controllers, strikers is for a 5 person group?
To give additional information, everyone in the group has runic weapons that level with our characters and can have crazy attributes and effects (GM made these up). He likes the concept of us being more powerful than average heroes and consequently pits us against way larger monster exp and/or monster levels than the books say. So far everything has been balanced on the whole. We have 2 role-player style players, 1 powergamer style player, a strategist, and a nuker type if that makes sense.
Our GM bounces between stringing several short encounters before an extended rest and at other times does a single hard encounter followed by an extended rest. He isn't really the type to kill off a character if he can avoid it, but he almost always tries to follow the mentality & tactics of the monsters he has pitted against us.
Our current party is as follows: Deva Wizard - mostly AoE spells or utility style stuff such as mass resistance Shifter Pally/Cleric - he uses 2handed mace and his heals up his defence considerably. he also has healing hands and lay of hands (not a legal build btw) Shifter Beastmaster Ranger - 2handed ranger with pet paragon path Tiefling Dragon Sorcerer - Acid orbs and heavy damage is her schtick I play a battlerager fighter/barbarian - he's badass because we don't play with errata (he can defend against nearly anything and has spiky damage occasionally)
Hope this helps. Let me know if you need more info.
