Oh boy, where to begin...
- Spiders!
- Ghost heat - I can't believe this failed experiment is still in game. No, seriously - it is one of the worst ideas in the long, sad history of bad ideas and it still got implemented on top of that
- The heat system in general, with its ludicrous low dissipation - even 20 DHS barely manage heat intensive loadouts like 2 ERPPCs/LPLs or 4 MPLs. Try squeezing some DPS out of those? - well, you MAY be able to fire 2-3 times, depending on the map, and then just run around cooling off while the opposing AC boat tears you apart with almost zero heat. WTF?!
- The PPC projectile speed nerf - these were the only weapon that allowed me to hit stuff with some semblance of consistency and now they're {Scrap}. On the other hand, the Gauss rifle now allows me to consistently hit stuff but... see below.
- Gauss rifle charge mechanic - we played with it, we didn't like it, now please PGI, can you just remove it and increase cooldown to like 6 sec or find some more adequate solution to achieve the thing you hoped to achieve with the charge-up.
- The movement mechanics change - I shudder to think how many times I've died because I was stuck against a ledge
ankle high. Come on, these are giant stompy robots and due to their stompiness they should be able to traverse obstacles like fist-sized rocks and such!
- The hit reg problems - ACs, Gauss and lasers are mostly fine, but everything else is basically useless with the 130-ish ping I have. Err, did I mention Spiders?
- Most other things, mentioned by previous posts. And Spiders!
