i agree, the drop low considerably, no boost, no supports, ( u need play sooo much games for get support) if u have a drop all times obtain Naval Mine x20-HQ-Potencial and if u have a lucky Veteran+1 and -1 T_t please check drops and rate for drops.

Actually both Blitzkrieg and GB xp are boosted. But the boost and xp you get depends on your crew level and the difference between your crew/Ship.  And the random drop prize have a big range, from experts, premium ships, credits, points, HQ, elites, smokes etc.  So basically you just have to play and stay in battle for 5 minutes, other than that it's all luck and random. 

And since EBB 6.5 or above are event only. So I don't think the statement "no chance to earn something good."  is invalid. 

Every event there are some players think it's good and some think it's not good. We can't please everyone.  And I believe everyone will agree that new players will help NF in the long term. This event as a pre-steam event. I think it will help us create an environment that is friendly for new players and at the same time provide good opportunity for old players to get event ships and grow their existing/new crew with awesome long time XP boost. 

I think a specific room should be created for players from level 61 to 75-80-90 there, with an experience of blitz or gb only for those bb1,2,3 can attack too, because in a match of gb novices Of bb's only take the leftovers of the bb5-6-7 and I think this is very unfair, because if you try to attack from bb1, it's the first sight of adversaries
