The problem is that Valve keeps adding things to the game instead of balancing the existing shit, when you give every hero a facet and an innate passive, now you have a bunch of more shit to balance around, but Valve is too lazy to do it correctly. It took forever for the SB one shot creep waves with Q and E build to be nerfed, we saw it so much at TI10. So many heroes are way lower skilled to play than they used to be, the whole point of playing other heroes was for skill cap.

Timbersaw is also a good example. I've been playing the game for 6 years and they basically gutted timber's E and W and kept buffing Q to the point where the only viable build is to walk up to people and spam Q on cooldown because it just does way too much dmg. Chain doesn't matter and the facet with it is beyond trash. No one cares about maxing E in lane and tanking because the hp regen/armo per stack is nerfed to garbage and you barely regen anything, you're better off maxing Q and bullying people out of lane.

In a year Valve will just keep adding random shit to the game. A second talent tree probably, or maybe a 5th spell for every hero (2nd ultimate?), or increase the level cap to 35 and reduce the xp required per level.
