So far I have got my Tiger I elited with and elite 3601 and PzIV.
Been trying out an A-20 to see what its like, and so far Im liking the speed of it.
Drum you will have fun in the tiger, the long 88 doesnt do the same damage as its counterparts but it has a faster reload and the thing is like a sniper.
Don't use it as a brawler unless you are near top tank, shots dont bounce and your modules are made of glass. Its better use is as a mobile TD, use your acc gun to track higher tier tanks and take out their modules.
The tiger overall wont lose you credits, but it is very slow to build them up.
