We waited for Grimoire, we can wait for this.
Very interesting analysis and from my experience, it's close enough, except if you roll your fighter and thief right, they'll hit things right of the bat.
At least for the fighter, i can't recall if the thief class was in the alpha builds i played.
About skills requiring other skills, it could be problematic, one quick fix would be either to increase the training speed of tier 2 / 3 skills or to have them start from level 1, 2 or more...
As for the traveling tediousness in order to come back to trainers or even shopping for that matter, i concur, we need some lloyd's beacons here.
And not the M&M X version, the M&M VI version allowing to set multiple (a lot preferably) different positions to return to.
