It's too slow progress and get you to spend more tokens and gems, no doubt.

Lower your defense a bit if you don't want to lose too much rank or lower your defense a lot if you want to best way more teams, it will help plus you help others too My Balance Now.

What rank  are you in?  Team  power  only tells  you so much.  My  team  in  G4  is  around  150,  but  it's  fast  with a  very strong  nuker.  Typically  those higher power  teams  are  tanks  with higher  resistance  and  defense  but  slower  and  possible  weaker  hitters.  

You might also want to look at your player power and compare it to the teams you're up against.  They should have a consistent player power compared to you, and if this is the case then it means you are probably hoarding a lot of champions, especially onces equipped with artifacts that you aren't using.

This isn't to say that you should start to get rid of champions, but you should definately consider getting rid of duplicate rares and below.  Also, if you have a lot of champions equipped with artifacts that you aren't using (i.e. they are legacy champions no longer in action) then consider at least removing the artifacts

You absoloutely can kill teams 100k more player power than yourself, i could ignore player power and instead consider the opposing team composition and what it is likely to do.

Team power does not mean a lot, it's more about comp and counters. This team was about double my team power but I beat it pretty easily with a counter comp.

That void lego you have 'leorius' causes me all sorts of problems, not sure how to counter him.

He is amazing tbh. To counter him it's same as a skullcrown, you need a block buffs to stop his unkillable or a champion that ignores unkillable. He can't be cc'd until he uses his a2 which causes trouble as well, because he is pretty much always going to get that first nuke off and it's a pretty massive nuke.

I'm a huge asshole and run him and skullcrown in the same team. 

I dont mind skullcrowns, i just stun/freeze them - yeh i can see how block buffs or putting skills on cooldown would work though

Thanks for your input guys. There's a lot to think about here.

I may be a little bit of a hoarder 😁 so I'll start there. 

When I see the opponent uses a Skullcrown, I bring Peydma. Buff stealing anticipates Skullcrown's unkillable and steals it "before" it's even placed. Means Peydma's A3 can one-hit Skullcrown from full health and Peydma is unkillable after doing that.

I didn't test it vs. Leo yet, but it should work the same way. 

The fundamental problem is that the "power" number is a fantastically unreliable indicator of the team's actual strength.  I think it overvalues ATK and DEF (the former is literally functionless on non-ATK champions) and undervalues speed, which is the key stat in the arena.  The team that goes first wins probably 90% of the time.
