It's not noobish at all. And stel you could just melee then when they walk at you.
Don't you think i do that lol?
The problem is these guys can turn any amount at any speed while maintaining perfect aim. Thus it's not so simple to just melee them nor can you expect them to be in melee range... Nor can you expect to be able to melee them 3 times before you die. I don't think it's up for discussion wether this is the noob thing or not considering this is, as i said, what you see alot of people solo. They can't use anything else (even with lock-on) so it shouldn't be hard to see really
(Seriously you see more people only using shotgun in this game, than people only using mp40 in MoH and CoD - i'd gladly bet this number would be considerably reduced if the game didn't have lock-on)
That's not to say it's an unbeatable strategy (far from it), but it certainly is the most fruity part of the lock-on. Shotgun would work much better and be a much more respectable weapon if lock-on was not in this game.
