I'm on the tortoise right now and having a blast. If anything save any free XP to upgrade the cannon once you get the tortoise. I thought the AT15 was fine, but the lower tiers are better because the front armor bounce more in lower tiers.
The tortoise without the top gun is really frustrating to play.
The tortoise plays quite differently because you seldom bounce anything, but still can take a beating. In my experience avoid close hill battles at all cost, as you weakest spot will pop out before you get to take a shot on the enemy. Very good on the distance and good damage dealer if you group up with a couple of brawlers in city battle.
yea right here, don't expect to bounce anything in the tortoise, the commanders hatch and to the left and right of the gun mantlet are easily pen'd w/o having to use gold. what saves you is the 6sec reload + 2000hp. so you can certainly beat almost anything 1v1 (wouldn't try against a medium tho heh)
