@overdead, don't know how many dex tm you knew before this balance change, but for me there was no way I would not see at least one dex tm in 2vs2 everytime.
Dex BM was a rare bird that now will just extinct.
Guess most will go for support tlm after this in 2vs2. Heck, maybe even high hp high strength TM works now. Damage > Defense in 2vs2.
