My point is it deal damage more than late game unit .
I never tell I can't deal with it.this is just unit stats nor player skill.
you guy never answer or put a fact always pulling other unit to decussion that out of point.
That is asymatrical balance, something Relic is famously known for.
The 'late game' unit you refer to has a lot more armor and HP, plus another gun (thus its fire damage can be a tiny bit less than the 251). The 251 is reasonbly fragile and loses other abilities in trade for its flamer. The WASP has possibly less flame damage cause it's cheaper and arrives earlier.
There are a ton of reasons why some units are similar, but still different. Also; take into account which support units each of these unit
can have (AT-gun vs. 251 = effective // AT-gun vs. KV8 not as much).
That is why we give you the counters for each unit. Since that is the only thing you can use to compare a certain unit with. If the counter is not sufficient, we should change the unit that causes the problem. That is where Elpern has a point; AT-guns tend to miss light vehicles quite a lot thus their target size should increase a little.
