In some respects I understand your POV Ass.
When I first played 2.9 I thought "Oh my god...what have they done", but as time went by I began to appreciate 2.9 more and more, and after I played my first clan-match I loved it, match-play shows 2.9 in all it's glory, the tension, the teamwork!
I personally played Inf for the realism...I was fed up with UT/Q3...2.86 gave me a nice balance of realism and fun but bunny-hopping-shotgun-hipped-robar was my major gripe with 2.86...(I never played RAv2 as my weapon of choice was M16 c/w ACOG+M203 (never used the acog for firing M203) but I couldn't use it in RAv2), but after 2 days of 2.9 I ONLY use FAMAS+ACOG now, funny how things turn out
Having said that however, I do miss 2.86 for a couple of reasons. If I had 20-30 minutes to kill I would quite often hop on a 2.86 server for a bit of a blast, a bit of fun, but I don't do that with 2.9 as I will probably spend the first 10 minutes waiting to play on the server watching the clock tick down, waiting my chance! So I normally load up FIFA or summat unless I have an hour at least!
I also miss a lot of the 2.86 maps, Chasm, Siberia and Kazakhstan (I lived in Saudi Arabia for many years and all the desert maps are bringing back too many bad memories) I want more snow maps
But in no way would I want to return to lean-bugging, hill-bugging(still there but greatly reduced), bunny-hopping, deadly shotguns at range, hipped robars and the "haha..I'm top of the scoreboard you must suck" at the end of each map that 2.86 had!
