I've seen another speed rook variant they took an early point in structural transfer. Very annoying.
With the speed, you get around the main weakness of this skill, the ease of being interrupted. You attack, disengage, heal and then come back to battle a few seconds later.
Considering how little armor Rook has, and how much less life speed rook has, I am wondering if its worth it to take archer tower/ tower of light early since you can't really stick around in a prolonged battle?
eg: Speed, In, boulder, slam, withdraw, heal. Repeat until later when you've bought your life higher with items.
Possible early build to experiment with to see if this hammer and run Rook actually works out...
Tower I
Hammer I
Structural I
Hammer II
Boulder I
Now to be clear, this is not to say you won't eventually take arrows and tower of light, just that you will take them a bit later then normal when your life is higher and you can stick around to make their damage output worthwhile.
And hey, since you can choose to melee, gauntlets of brutality?
