The melee is definitly the main reason I play this game so much. It has its faults, but all in all it's still very much about skill and tactical play and thats why I forgive the mistakes.
I also like being part of a regiment, participating in its events and reaching my goals within the game or the regiment.
Another big plus, was tournaments hosted mainly by Hekko. Sadly this positive point has gone and noone seems to be willing to put in the hard work, Hekko had put into this communtiy. Perhaps sooner or later someone else will decide to take up the organising of a GF tournament or NWEC or something of that sort, since I do think lots of the big fans miss it, including myself.
