So basically I finally stopped procrastinating and upgraded my 2*defender all the way to 4*. I don't play on weekdays (Mon-Thurs) but when Friday comes around, you bet I'll be trying out a T3 gate.
Is the jump from T2 to T3 just as shocking as the jump from T1 to T2 (Oh no the monsters actually do damage now!)?
Is there anything at all I should know about in terms of contrast between tiers 2 and 3?
It is a big jump, in my opinion. You'll now get the full elemental and shadow damage.
