That's me. I discovered it in February and all I can say is that I'm addicted.

15 players on a side, pure fun until Tier 5 maximum 6. After that is not so fun but is fine for me.
Tip: play Russian whatever you like. Almost all are slightly overpowered (for meds T44/54 are some kind of UFO's, for TD's SU-85 is a joy and ISU-152/Object 704 are killers and for heavy IS line is deadly).
My goal was Tiger/King Tiger so I've made my way to them but what a disappointment. So I've switched to Russian TD line. SU-85 is pure fun and now I'm struggling with ISU-152 (need some upgrades though).
Artillery is not my kind of play and I HATE it.

Second tip: made your crew 100% and search for secondary skills. It's like day and night between 50/75% and 100% with secondary skills. Also buy modules (loading time, aiming time, crew skill boost, binoculars, camo net, etc).
The game have some serious drawbacks with matchmaking system and spotting/invisible tanks and you need to pray to have a good team but in the end the game is fun. And the best thing is that is free to play even after April 12 when it be launched officially. You can buy gold if you want to upgrade fast but if you play for fun you'll have same tanks but in more time.
