skill tree

Suggestion for new skills in the skill tree. Earth Mastery: [icon]Earth Mastery +1 range for enchanted tiles. (in depth description: it adds range to the enchanted tiles that already has a +1 range. The skill will +0 range when skill mastery is from 0/10-4/10, +1 range when skill mastery is from 5/10-9/10 +2 range when skill mastery is 10/10[ this might be too much haha])

Sounds awesome, but overpowered :P However, would definitely open up more towers to be carries, like the Frog.
