Pros: Clan mechs Seriously who doesn't want these machines stomping their badassery around the battlefield whether it is your prerogative to pilot them and go "F*CK YEAH!" or to shoot the living sh*t out of them and go "F*CK YEAH I KILLED A CLANNER". Cons: Poor implementation. Honestly the trailer looks like crap. they added fires to the buildings. That is it. As well, it won't feel like an invasion unless something changes quickly within MW:O, which of course I remain optimistically hopeful for.
This is why I dont game much anymore. Back in the day, my 2 favorites were free mods for halflife (CS and DOD). America's Army was free. Starcraft let you install the slave version on multiple computers for LAN parties. Heck, even WoW was at least cinsistent; $15/mo for access to ALL content. Now, everything is microtransactions. You don't even realize how much $$ you drop on the game until you get your credit card statement. Instead of fixing the problems or adding more content, PGI adds more mechs that do the same thing. At least dropping this much money on an MMO means you get dozens of leveling zones, thousands of enemies, dozens of categories you can collect, solo play, pvp, group content, and probably 2 to 4 patches with all new content. MWO has the same few maps with just new mechs every month.
