While keeping things fresh is a great idea, I just got triggered as soon as you threw in open world PVP and games like Aion with FFXIV. I'll stick to Aion since I know that game best out the ones you listed- however its core game design is nothing at all like FFXIV - it was always designed as a PVP/PVE open world game with almost no safe zones for most of its history aside from its version of dungeons. Currently, its class balance is terrible, although I agree healers are currently strong in PVP.

I far prefer a game that separates PVP and PVE skills since I have seen too many cases where a job is well balanced in PVE but underperforms in PVP.

In addition, while I abhor bots I never was interested in spending my timing cleaning them up through very boring "PVP" against a bot. I'd rather stick to reporting them.
