While I am sure for high level play every little change is a huge deal, for me as a casual CS seems much the same as it ever did. Most of the changes you list would only seem like "big changes" if you are a high level player who knows the whole thing back to front and have memorised recoil patterns and whatnot.

when you start with a game that basically revolves around the delicate balance between five weapons, even subtle changes to the mechanics can make a very big difference to the way the game is played at all levels.

I know you probably don't care about things like movement accel curves or hitbox sizes (which have changed drastically over the years) but just look at the deagle, possibly the most iconic weapon of the franchise. the weapon went largely unchanged between 1.6 and source, but is almost unrecognizable in csgo. you simply can't use it the same way you could in the older games; it has a completely different role.

the game isn't that complex, if you play for more than 5 hours a week you'll become one of those "high level" players and notice the changes
