there's no such a thing as a party that works for every single situation, simply because PvE is PvE, and PvP is PvP. every single class has its own utility, some are better at PvP, some at PvE, others at making adena. you can't possibly have a party that works in both situations, simply because if i have to take PvE as an example, a party without a proper tank and a proper healer will get rekt by raid bosses anytime. same thing applies to a PvP party without a proper healer and proper dpsers, they'll just get rekt by other groups if their class setup is wrong to begin with. You really think you will do a lot of RBs on Classic? people playing in top clans will for sure. i myself am not a fan of PvE, but i'll do RBs if i have the chance to get gear faster, instead of wasting my time gathering materials/crafting. That's delusional. First of, you will need like 2-3 parties minimum because no one will have gear, buffs, pots, nothing. Secondly, with the ridiculous drop rate what are the chances something good drops. Thirdly what are the chances you will get anything. Even people in top clans they don't waste time on normal RBs, only epics like Orfen, Core, AQ.
