And your views however valid can be completely dismissed. TFU is a part of Legends canon, whether we like it or not. What Galen has accomplished throughout the series canonically happened, so trying to take those showings and power-scale them down is a murky task to say the least.
FOTJ Luke is clearly above Vader. Caedus is a little ways under FOTJ Luke. So for example: Luke > Vader = Caedus > Starkiller which would powerscale SK's feats to below Caedus's minimum.
The argument could be made however that: Luke > Caedus > Vader > Starkiller. Which would put Starkiller considerably below Caedus.
Feat wise however Starkiller pretty much trumps all of them even Luke. This leads to a paradox in the cannon. As a result I power scale the feats from a sensationalized game intended to sell based on crazy use of the force instead of good story telling. You can do the opposite if you want, just be consistent.
