Due to the fact that they didnt model any decent ECM or ECCM in Mech 4 it was easy to win in multiplayer, you just loaded up with Arrow IVs and faded everyone to death.
I think for "feel" Mechwarrior 3 wins hands down. The Mech 2 games come second, and the Mech 4 games I always placed last for how they played with regards to reload times and how the weapons and systems worked.
Nah, the Arrow4 was a line-of-sight weapon really. While LRMs would go just over the top of a jill the Arrow4 would try and get through the middle of it.
I used to spend most of my time hunting down jump snipers and poptarts, because you know, it was funny listening to them whine. Even more amusing when I was doing it in a Raven with a Clan Flamer and 2 Arty Beacons. Jump snipers hated that config with passion, because it usually blew all their guns off. They also couldnt ignore you because if they did they would be dead, but if they concentrated on you they would be swarmed under by the other members of your team. For Brawling a Thor with 1 CLBX10 and 2xCLBX20 was killer config in a brawl. If you wanted to just be really annoying then filling a Masakari full of CLRM10s and chain firing caused ANGER, it was even more fun if you got a spotter up with some NARC Beacons, you used to stay passive, wait for the NARC and then fire off everything in one go, I used to spend a lot of my time NARCing people in a Raven for my Gaming Team to then wipe them out.
