There needs to be more Clarity!
Champion stats are probably the biggest offender in my opinion. There are 5 lanes each with a given value for each champion. There is also a lane stat to go along with that. So what determines how well a champion can do in a specific lane. Well you would assume the highest rating in that lane means they can do well, but then you have champions who are split like Kayle. Kayle does fine mid lane as good as any other champion, but that's not what the stats say. She mediocre at every position which is not true. Is Kayle just going to be one of the worst champions because her position stats are terrible? That's what I would assume from the stats. What does a high stat in a position even do? We already have a laning stat so it just amplifies that?
There are a lot of champions who do just as well mid or others yet are severely under rated because they can be played in other roles. Probably needs to be changed or explained how I'm wrong and it tells me how that stat works.
More confusing elements with stats for champions is magic and physical damage. From first glance I would assume the higher stat in a damage type means they scale better with that damage when you build them with it. But if you look at someone like Corki he has mediocre physical damage and mediocre magic damage. But he scales fine with AD just as much as most other ADC's but that's not reflected in the stats. So there seems to be another problem with hybrid champions who do multiple things. And if I'm wrong it needs to be clear I'm guessing at how this game works which is never good.
Even more problems with champion stats. How does CC and utility work now? You would assume CC is utility but they are separate so they must do separate things. If I had to guess it would be that CC stops an enemy from moving and dealing damage randomly. So they higher CC the better someone is at jungling or stopping a carry from doing damage or saving your carry from damage. But it could mean something completely different without a better explanation from the game. Same goes with utility. I'm pretty sure now utility means it heals other champions but how am I meant to know that from reading utility? Same goes with utility in the build section.
I can go on and on and on about clarity in this game, but I think you get the point if you have read all this. I'll make an easier to follow list below.
1. Champion stats, all of them. (When I hover over a stat EXPLAIN what it does)
2. Utility in builds. Utility could mean anything, explain what it does.
3. Players energy and how it effects them.
4. PR managers. What do their stats mean? Explain.
5. Players age not added but when it is we need to know what it does.
There are probably a hundred more. I'll say it again there just needs to be more clarity. No more hidden information please.
