& the abusing of power in continuous pathway -

Why The difference Develops/upgrdaes of tanks & hulls so slightly & very disappointing , Sreiously feeling there's no difference between low ranks and high ranks , Like feeling what's the point of developing my tank In The First Place , at least the develop that i wish when i try to do it hopefully that would make difference about 75% to 50% than the primary one's :) , Or like each develop should be like that , But What we're having it's like so insignificant enhancement whether armor ,Or Fire rate ,Like' THE MAXIMUM ENHANCMENT' of this game FOR ALL TANKS AND HULLS LIKE 80% OR Less ! !! THAN the original , It's just so frustrating :mellow: ..
