Nah, I watched some gameplay on youtube and figured out pretty quickly that the dual ER LL sniper/ECM build on the Raven 3L would be my go-to. It's been a blast to play and I rarely get below 400 damage.
The problem I have with MWO thus far is exactly what you've outlined: they're too aggressive about the microtransactions, even to the point of mimicking Wargaming's bullshit about "lol we have ten bajillion vehicles but you're only allowed to own four unless you gib shekels". At least it's "only" $7 for 12 more slots.
I'm honestly not sure if I totally agree about the grind, though. I've only been playing for ~3 hours and I've already got my RVN-3L maxed as far as I can; I've got all the basic skills, the best XL engine, all the hull/heatsink upgrades bought, and my ideal loadout in all other respects. I've got enough C-bills to buy the next variant, and I ought to be able to start unlocking elite skills in 7-8 more hours max. The only part that's blatantly grindy is the pilot skills because they think they can fleece people of more cash to convert exp or whatever.
It's not a great game, but it's recognizably a modernized MW game. I've got my real hopes for excellence pinned on the tactical/strategic one that succeeded massively on KS just recently, but that's a year or two out and MWO is an acceptable stopgap.
