Any template in SOD is an unbalanced mess, if you want to know the truth. Skirmish, Balance, and Panic are definitely no worse than the same old mini-Nosty, not to mention Anarchy.
In general, the imbalance of templates is a very cool concept, invented by "daddies" to force newbies to play templates that are convenient for them, such as HL+U or Jebus. I, for example, have played quite a few games on M and L, and I can confidently say that they are no less skillful than the same 8mm6a, which many people love. And the same M200 tournament with fixed castles and heroes will say much more about the player's skill than HL+U on a full random map.
p.s. for once, I completely agree with Wicc's post
