Yesterday, I found CoA and with the promising x15 exp (which, despite hating leveling, I consider too much), not being pseudo p2w and last but not least the supposed crash fixes, decide to give a try.
I knew there is a NPC to auto level up to 80 with equipment, but when I watched the equipment, it seemed so powerful I had the feeling that its was going just an easy trip to last dungeon. Even more, the feeling that dungeons are just full dps without any mechanic.
The super fast leveling plus that kind of equipment makes me wonder if the game is just a "summer game": play it for 3 months, get to 100 do all dungeons in "god like mode" and more or less the game is done and I don't want that.
I'm actually playing RoM and there are the differences are so big... t13 weapon? be inside the wheel of money generation or spends months of time to get it. +16? no way unless some players sell you (gift you) diamonds (or real money).
It's like RoM -> Hard mode farming vs CoA -> click'n'go or "hack'n'slash"ish.
Have a good day.
