I can compare movement speed. The average movespeed in dota is pretty close to 300, where the average in league is closer to 315.
I mean if we wanted to compare other things (vision range? Map size? Collision size of units themselves?) we could make those comparisons.
I meant to write something about average ranges in dota compared to league, but I removed it as i felt it wasnt important. So..
In dota, melee range is 128. In league, its 125. Exceptions are heros like doombringer, and I think xin.
In dota, drow has 625 range. In league, ashe has 600. Ill grant you maybe 50% greater range.. but silly comparisons like "it takes up x% of screen) is kinda silly. I could post a picture all zoomed in saying blitz's hook clearly goes offscreen.. but it simply wouldnt be relevant.
On the other hand, comparative movespeed is relevant. Comparative ranges is relevant. Both of these are honestly fairly similar:
It takes ABOUT 3 seconds for the average league champion to traverse the distance blitz can hook.
It takes ABOUT 4 seconds for the average dota hero to traverse the distance pudge can hook.
THAT is the core of the comparison I want to make, and possibly the most relevant one when you compare the raw numbers; And most importantly, I am comparing dota to dota, and league to league.
That isnt to say I wouldnt agree that the map is designed differently that 1300 units in dota means a lot more - if you look at mid, you can pull someone within their tower range well into your tower range, across highground.
In league, blitz's pull is at best a short-midrange initiation that often is honestly nullified by flash (flash having 400 range, and can go across any wall if done right, which is usually what blitz does - pull someone across a wall)
