Wow, what a breath of fresh air! I am not leaving MWO for WoWS (you guys aren't THAT lucky), but there are several mechanics that I'd like to point out that could be beneficial for MWO. Not carbon copy brought into MWO, but worth looking at.
Convergence. Wow! Convergence is HUGE in WoWS and it takes time. It doesn't detract from gameplay at all, only added to the immersion of the gameplay.
Multiple reticles. For anyone saying more than two reticles in MWO would be too hard, I say it isn't. In WoWS I had up to 8 reticles and they were all identical and overlapping and it didn;t bother me one bit.
Survivability. Battleships FEEL like battleships. Take a beating and keep beating back. Even the destroyers (aka Lights) felt tanky but were also fragile. Many times I maneuvered close to something hurting me a lot just to get a guaranteed hit with my torpedoes. And those torpedoes HURT!
Balance. Now, I may not have had a long enough time playing to get a comprehensive feel for balance in WoWS, but it felt right. My I didn't feel helpless using any class of ship going up against any other class of ship. I didn't feel God-like either. Torpedoes will make short work of any ship. I didn't spend any money on their premium ammunitions (P2W IMHO) but I never felt like I needed them. Otherwise, all weapons where the same, loadouts the same, etc.
Features. One feature I really like was the F# key chat responses. Most of the F# keys had something like "Affirmative" or "Negative" or "Help!". One even had "@(*$^&#$(" that also had voice like a comm channel. Really neat. I will say that their UI wasn't as user-friendly as I would have hoped. Wasted some money on some mistakes so the grass isn't greener on the other side.

This is NOT an advertisement for WoWS or meant to sway players to that game. I played something different and it inspired me to want to help MWO be better. I thought WoWS was a good comparison because of the relative likeness between the ships and our mechs.
