If you like lags - you will like MWO.
If you like netcode problems, lagshooting and weapons with random fire delay up to 2 seconds - you will like MWO.
If you like grinding money on one and the same 5 maps - you will love MWO.
If you suck at handling your mech in battle and manoeuvring - you will love MWO (with its small maps and narrow passes, where mechs can't even circle strafe).
If you have problems with visual recognition of enemies, but love seeing world in tones of blue and green - you will love MWO's IR vision (otherwise - too bad, you will still use it 90% of the time).
If you love boating - MWO is your game. 6*PPC Stalkers and 6*SRM6 Catas will be you friends!
Oh, BTW: I hope you love having next to no weapon balance, where AC5 has the least DPS of all ballistics, UAC5 has more DPS then AC20, but jams randomly and AC2 produce as much heat as a PPC.
I also hope you hate ER energy weapons, since screwed up heat system makes them useless.
Well, those are major points why I hate that game. It tries to get rid of as much skill as possible by introducing a lot of random numbers and small stupid maps.
One could play MWLL for several months and still learn a lot of new things. One can learn all the MWO mechanics in a matter of days.
I was playing in MWO a lot, when it still was in CBT. I got bored before it got out in OBT. Also, lost any hope for a better game then.
