Strength OP. We need better reasons to go for Dex bots, and because the block percentage maxes out at 70% that's pretty much our only advantage over high-armour bots gone at higher levels. Additionally, there aren't very many dex-based weapons which are equippable. There's one or two, and several in the lower levels, but in between huge gaps in level.
So, incentives could be critical hits, dex-armours (not a good idea), more shields, unique white shields, higher block percentage caps, etc.
