Zerg Tyranolisk.......!

it matters because the unit is based on a t-rex so it has everything to do about it

 

No it's not.

The only thing about this new unit that it shares with the actual T-rex is it's size and it's name.

And besides, units don't have to be like their namesake in every way. The Hydralisk doesn't have seven heads, the Protoss scout is slow and loaded with firepower...etc.
