Volibear Rework Suggestion

Volibear is a stale as champion, he sucks right now, let's make playing him fun.

W - Now stacks up to 6 times, 3 times to use the ability and 6 to restore cd of the ability. (Numbers obviously adjusted)

  ex:
      normal cd is 12 seconds instead of 18, the damage is reduced significantly to compensate, but at 6 stacks the cd is 4 seconds.
      Still has execution-like ability.

R - Now applies a stack on each enemy hit by the lightning, at 4 stacks applies a mark where being bitten by volibear's w consumes the mark and does extra magic damage.

  ex: Volibear is in a 3v3. He uses his ulti and starts autoing peeps, and now each of the enemies have been hit 4 times by the chain lightning. If volibear uses his chomp on one of them, it now consumes that mark and does additional magic damage. If he had 6 stacks of his w, it would have reduced cd. Now that the mark is consumed, he can get reapply the mark by hitting them 4 times with the lightning again. 

This change would make** volibear scary in a sustained fight** but not make his gameplay super complicated (you just auto more) since most volibear players probably like his simplistic playstyle.

**Volibear is already pretty easy to kite **so there would be plenty of champions that could play around this, if this would really be too strong then I would increase his q cd or change the number of stacks required.

Please consider this because volibear was one of my favorite champions before the unnecessary nerf to his early game and the removal of sated devourer.
