yeah kinda. I think that a power that you attack upt to 3 targets for 1W that yyou can trade out at level 17 to instead hit up to 4 targets for 2w could just be the same power with a rider "at level 17 increase to..."Except a lot of the new powers were the same power with higher numbers.
4e was rushed and very raw. It had GREAT ideas (and is the best edition of the game so far for me) but it needed work. Essentials started to get it better, and some 5e improvments and ideas grafted back on to a 4e frame work would have improved it more. Having said all of that I still think WotC abandoning the good of 4e to step backwards for 5e will always be a soar spot for me and my friends... I really hope someday 6e will take the 4e ideas and some bits of 2e, some 5e ideas and rework them all into my perfect edition... I can live in hope
