Unit Variety

It is a step forward. We now have a new unit that I believe will be great for the game once it's properly balanced.

As MrTBSC said:

First implementations of balance are often not that great – that's just how balance goes. The idea is great, the current implementation not quite. Next balance change to them will mean they probably become underpowered. And then after that, more true to what they should be.

That's how balance goes.

Don't entirely dismiss a new unit because its first implementation isn't perfectly balanced.

Acknowledge it's issues, acknowledge its strengths, and adjust accordingly to achieve an ideal balance.
