About the level cap, I wont lie, I like it even not knowing what it offer to us beyond more XP to farm. My main concern is at least in PnP and also other D&D eletronics games i've played from heroics to epic and than to legendary levels the adventures get a bit annoying with all those resistances and immunity that monster gets. Hope we get in the mood of legendary adventures , time for plane and time travels as also meeting some other famous guys such as elminster.
Getting into the hamster wheel is a option and TRing is not so different than sitting on level cap and repeat same raids every weeks. Personally I do prefer leveling again slightly stronger but thats because i do it with no rush =p.
I'm on a ryzen 5 3600 + a gtx 1070 card and I'm having some random crashes and frezees on ddo. It used to happen on My 4th gen i5 too(but less frequent). Have no problems playing other new and supposed more hardware intensive games at all , also no issues working on blender ( a hardware intensive application) so i guess its an ddo issue but i did everything in my power to solve the problem( reinstal, move to SSD, read forums) without any success so I hope 64bits client can solve it .
