I really hope ND increases the cost of paid boosters so that it is not reasonable to purchased them each round. I bought the Ping booster to test my fears about the return of SA (after some level 42 player kept killing me when they could not reasonably know where I was) and sure enough I get to see through walls for the small cost of $25,000 a round. Making more than that in a round seems pretty easy. Once people have purchased all of the relevant upgrades this booster will probably be abused all the time. Sure, Hardcore is an option, but I prefer objective game modes.
It is already bad that regular boosters only get stronger as you level them up and do not have any counter balance.
Played a game of Plunder last night with Weapons Expert/AK/Para, Back in the Saddle and Speedy-G on Yemen. I didn't even bother aiming down the sights and never stopped moving. I got 3 five not alive medals and ended with 62 kills and 24 deaths. Despite my rampage we only tied (playing with randoms, 2 of which did nothing more than snipe and die a lot) as we were playing against a 5 man party. The other team kept bitching about me lagging, but I only encountered a few moments in the match where lag seemed to be an issue. Blindfire with the AK is obscene and with constant traversal it is easy to get the drop on people.
Weapons definitely need balancing and every buff should come with an equal compromise.
Traversal needs to be tweaked so that you actually grab ledges instead of just bouncing off the walls (Air strip stage 1 is complete crap, if only because of this - well, that section is just garbage regardless of traversal). For a platforming game, the traversal is very weak and a gamble to use in many situations.
Auto aim needs to be nerfed and camera movement speed needs to be increased. Blindfire with shotguns, pistols and AKs are just auto affairs right now and require no skill (see my above score!). However tracking people at close range with the camera and having the gun shoot where the camera is aimed should still be viable.
Bullet lag is garbage - the G-Mal seems to have DtI equipped at all times. I am very tired of getting shot through walls constantly.
Spawing within proximity of an objective should not be allowed, period.
Co-op Hunters - such a garbage, me too, game mode.
Game is o.k. but, imo, it lacks the character of UC2 (beta and early release). I'll be payig attention to this over the next few months, but based on all the feedback ND recieved from UC2 and this beta experience I will be looking for a different MP game this fall. I have no faith that ND is willing to create an experience that deviates from what the gaming industry believes the MW2 generation will eat up.
