What's the point in reducing Blitzers to 80K and then upping rerolls to 60K. How is that a boost?
Humans are waaaay short of where (it seems) the majority of coaches think they should be. And where the fluff suggests they should be. Human teams have won more Blood Bowls (fluff only, not 'real' results) than any other race. By far. Humans have 8, Orcs 6, Skaven and DE on 4 and then some on 3.
In LRB5 tournaments Humans are 16th, with only Slann, Chaos and Nurgle behind. I think Slann will overtake them in short order once people work them out. But more importantly perhaps, they are not just 16th. They are a distant 16th. They have a Record of 0.438, 1.5% behind HEs in 15th and 3.6% behind Necros in 15th. Yes, Necros who have been massively boosted in LRB6.

At 0.438 Humans are way below of the 45% boundary the BBRC set to scrape into tier 1. And (it seems) most people believe Humans should do more than just scrape in, they should be competitive. Not at the top of tier 1 perhaps, but very firmly in the middle.
The league stats are similar. Record is 0.458, so they just scrape into the BBRC's tier 1. Yet the only teams below them are Necros on 0.448 (only just out of the boundary, yet
massively boosted), Vamps, Ogres, Gobbos and Flings. Where's the consistency?
I've played Humans in leagues (LRB4 and 5). I've won with them at low and mid TRs. But at high TRs they were too squishy and too expensive to replace. AG3 and no agility access is a death sentence against certain teams. Hence the price reductions I suggested. Without changing the dynamic of the team at all, you can add a further dimension ... i.e. a strong bench and the abilty to replace key positionals. This in itself will boost the tournament team more than leagues (desirable since they do worse in tournaments). But in leagues it gives a coach the option to play more aggressively. 90K is a lot to find at mid/high TVs even once, let alone regularly. Plus it just feels right ... Humans should be average and disposable.
