Gamerdruid is the most active moderator in this thread, yet the most clueless. Just reading his replies makes me cringe. Do you troll us or are you honestly that clueless about this game?
In a competitive environment that this game provides, you want to use every advantage there is. That means use Supply Points for TA.
So let's say right now in Firestorm 14 I have 1800 Supply Points. I would want to buy command points for them to maximize my account's growth. That's 1800/10 = 180 times I would buy command points.
The TA cost for buying command points is 247. SO 180 x 247 = 44460. There literally 40 bucks spent already.
I am getting 280/d growth rate of supply points so it will take me 6.4 days to recharge. Woah! Another 50k of TA for 40 bucks spent. Do you realize how insane that is?
Nobody can or should be paying this much.
Just to compare to other much better games, like world of warcraft, you spend 11 bucks for monthly subscription and you get constant game updates, lots of new content every year.
EA must be insane to justify these prices.
