I think we should give the bushes camoflage to every kinds of tanks. However, the tanks themself will be invisible and the bushes created in the followed ability will be visible.
So the enemies will be able to scout and guess whether there are enemy’s tanks in particular areas or not, in term of see some suspious bushes.
a. We already had in the past invisibility for tanks. The problem is, this lead us to an OP problem, specially with heavy cats
b. Debuf for enemy, well we already discuss this in the past with the team too but we decided with a small buff like it is in the actual state. I have the open mind in this point, if more people is agree.
