I recognize it's very early to criticize, and I haven't made completely made up my mind about the new map. My two cents:
1) With no jungle around Vilemaw, there's no mystery/excitement surrounding him. In the old TT, you'd see one or two people disappear in the top jungle and you'd worry..."Are they doing Dragon? Are they just jungling?" And you'd have to go check, and be terrified you'd get jumped on. I loved that.
2) With so many jungle entrances to the lane, any sort of laning phase is difficult. It is a non-stop champ killing fest similar to both Dominion and bad kung-fu movies. I think I'd like to see just one less entrance on each side...to keep that mixture of feeling safe sometimes and unsafe others...as opposed to being constantly vulnerable if you aren't near your towers.
