Let's see:
1. Shittiest grid and then line system they could come up with.
2. K/D ratios forcing people to cheese and do senseless farming, taking all the previous Planetside experience out of the window.
3. Atrocious resource system allows players to literally clog roads with tanks.
4. To combat the above, instead of fixing it, SOE implemented pants-on-head retarded pay-to-get atgm weapons that nevertheless do little damage and can only be used en masse. Shame no one organises in teams because k/d farm is more important.
5. Bugs, crashes, tons of other server issues, none addressed. Ever.
I could literally go on for 10 more and elaborate enough to fill the entire page on why Planetside 2 remains a bland and uninteresting game after the initial hype. SOE promised heaven, didn't deliver shit.
Unless you consider new, broken guns as worthy additions. In which case best of luck farming your k/d with Liberators at the Crown.
