The 50% off crew training is nice. The double credit income is nice if you happen to play those particular tanks. The M4A3E8 for example is a fun tank to play. I just elited mine though so now my interest has shifted elsewhere unfortunately. What I would really love to see is a weekend special or even just a 24 hour special where credit or xp is doubled for all battles for all tanks. And give an advance notice, at least 3 days and preferably a week, before doing it so people can plan accordingly to attend. That would really be sweet. Bet the servers population would hit new highs with that in play.
