I dislike Uplay due to the clunky and "social" layout it currently displays, I hate the bandwidth usage it has over Steam/Origin because at least with those two I can still watch a youtube video or browse the web in general, I can't do that with Uplay since it sends everything to the slowest of crawls (no I shouldn't have to "adjust" the speed settings when Origin/Steam do it right), I don't like having to launch Assassins Creed 2 from Steam only to have Uplay boot up and "sync" me with the games files which are already on my PC along with gobbling up a few processes (I like to have as few taken up as possible due to my current build).
Only redeeming feature from that client is Uplay points which I earn from certain achievements and then proceed to either save them up or spend them on the game I earned them on or other games, I like that feature and it seems EA's caught onto it too since I'm seeing them working it into Origin which would kill the last incentive I have from Uplay.
Not really fond of them doing this but in the end it's their game and they funded and created it so I'd knock off the "holding hostage" bullcrap (seriously it's easy to say anything is held hostage that I don't like these days), though them charging extra towards us in the UK just because they can earns a complete fuck off from me, no way am I going to accept that the US and other parts of the world can buy it for a regular asking price, the price they ask us is ridiculous, at best brand new AAA games here sometimes cost around £40 but they are asking for an extra £10 for fuck all reasoning, that's the biggest bullshit I have gripes with, they have zero reason to do this to us, giving us the "pricing issues" excuse is borderline insulting, there is no pricing issue with most games here (though we still get screwed but not as much as Aussies).
I do hate Uplay but I'm not going to hate the company like people do EA, I just hate the stupid as fuck decisions and the people behind them because all they do is earn ire and extreme contempt, after Watch Dogs and the ongoing crap about Unity Ubisoft is really fucking everything up, they even pandered to the PC crowd about the Division in saying they promised they would make it as graphical and promising to them as possible, basically the same excuse they used last time with Watch Dogs, seriously very stupid move and they should really consider firing and replacing the guys/gals behind PR because they've sucked at that for years now and it's obvious they aren't getting any better at it, also replace their crew that are supposed to be optimizing their games while they're at it.
