I got my comm skills up by going in ready to lose, so Id relocate, CONSTENTLY. But sometimes, (or eventually when the rush of simply just relocating wasnt enough, and I wanted to win) I began to comm a tad more serious, I got teh upgrades, I usually do the same thing, and lately Ive been comming some serious games and owning newbs (only if my rine team owns :-D ) Like today on ns_nancy, great team helps a lot, it was one of my usual spamarific games (not more then 5 s of silence from my mic!) and we did great, people listened, and when they did they got what they wanted like shotties and such :-D and as usual I go heavy, you comm with Bill, your comming with heavy!
on another note, ns_veil the next map I relocated to topographicle all hyped up and ready to lose, and we did just that, in so much style that the last 2 beacons into ms (which was FULL of oc's and instadeathed my teams almost both times) were things of hilarity, I was happy they had 4 fades and finished it quick.
But even when I serious comm, I med spam continuelessly, Youll get 3 medpacks at the least most times, I only raation when I want a building or such. good fun comming, just need to get into it first :-D
