1. The non-debug mode of COV will have very nice performance, like COH beta to Live shown us. COH performance is on par with WOW's.
2. IMO the combat model and encounters in COH when you are on a nice big team is second to none in the MMO genre. This is the part they really nailed with this game.
3. I haven't done a lot in COV beta at all, it does seem very similar and as mentioned it has to be somewhat the same as the two will eventually meet up with one another. I won't get this day one, but somewhere down the road.
4. The Enhancement change actually does add diversity to the game, it forces you to add different enhancements instead of a straight 6 of one particular thing. That is diversity. Sure it can be looked at as a nerf, but at the same time they have also give us back things as well. More group XP over the years, half debt cost while dying in a mission, boosted some powers etc. Too many just look at the negatives, it's not about being easy, only a putz wants that. You want a challenge with a fulfilling reward. There has been a lot of give and take and if things are to nerf'd then they will make an adjustment to make the game fun again for the base to play.
5. To the person who doesn't want to pay $50 and $15. Your boycott is failing miserably. MMO's is the PC's life blood these days.
6. One of the most important parts of a MMO in the design phase is how fast and flexible the code is for addons etc. This game like almost all of them so far have done a poorish job. Many of the things they wanted, haven't happened or been greatly reduced when the rubber hit the road. As these evolve making an engine that is easy to adjust and add content to will become more and more important.
Overall COH was good and over the two years it's done a decent job at adding content and honing itself. They weren't able to make any mind-blowing drastic changes and I suspect COV to go right down that same exact path.
