There's no cap to health regen right?

(RESOLVED) So gains healing based on flat amount x level, it's rather bad clarification to see her health regeneration number go up - which is very similar to using health potions, gradual healing instead of instantaneous like

There shouldn't be a cap, not to my knowledge anyway.

The new champion Rek'sai (yeah new champions are bound to have bugs or some sort), has something that came to my notice.

When health is below 100%, and burrowed with fury, she gains health regeneration till the fury is entirely consumed or health points are full. The numbers on the right side of her health pool should be increased.

So after buying Warmog's Armor , the health regeneration didn't stack each other while burrowing with fury.

These were the conditions that brought it up: -Health below 100% -Gained 100 fury -Not receiving hits to get off the cooldown.

I am sure this is no visual or clarification bug because the health regeneration stayed exactly the same amount after the fury is consumed. Yet using a health potion made health regeneration stacked normally. I still need to further test this or unless it was already discussed and it is intentional in the champion design. (Wouldn't want a 2.0 do we?)

tl;dr: 's health regen from burrowing with fury and don't stack
