I'm thinking about picking up some gold, I'm just not sure how much I want to grab. I'm not going to make gold buying a regular thing, and will probably just do it this once, so I'm really looking at garage slots and possibly premium tanks.
$15 for 3000 gold is a nice and cheap option. Probably would end up buying 10 garage slots, as I needed them. There aren't really any premium tanks at this level I'd really consider, as I can probably make as much or more money with some good tier 5 and 6 tanks.
$50 for 12000 gold is the more expensive option. I'd probably buy a Type 59 or KV-5, and have enough left over for 15 garage slots. I'd lean towards the Type 59, but I'm really not that familiar with the medium style of play so I am a little wary of spending a bit more than $30 on it.
The obvious solution is to hold off on buying any gold for now, grind up a medium line that plays similarly to the Type 59, and make my decision then. However, I'd really like some garage slots now, and spending $15 now and $30 later for 9500 total gold is really quite a waste. I suppose I could spend the $50 now, and just hold off on buying a premium tank... but that also seems somewhat wasteful to just leave ~$50 worth of gold sitting idle.
Plus there is the whole aspect of paying $50 for a free-to-play game, $30 of it for a virtual tank with the sole purpose of grinding money.
