Tried to post this on reddit, but yea reddit is full of hostile mods.
In case anyone is keen to try to simple low-spec and busy full-3D RvR open pvp war mmo, you may consider Champions of Regnum.
Other similar mmos include: GW2, ESO, New World, DAOC, Wow and so forth.
Of all of the above, Regnum is the closest to DAOC. Same 3 realm faction setup, same click to target combat. Regnum's gfx is slightly more advanced than DAOC. The others like gw2, New World etc, are known to have generally sucky combat.
Example of fort battle in Regnum:
Feel free to ask any questions. Regnum isn't for everyone, but just letting people know if case anyone is interested.
