Related Question: [Is Feral Warwick skin bigger?](https://gaming.stackexchange.com/q/57069/16007)

In the related question, I learned that different champions have different sized "hitbox." I also learned that Chogath, Nasus, and Renekton's ultimates can increase the size of these hitboxes. I also assume surge, greater relic and Wild Growth will also increase this hitbox as it increases the size of the Champion.

My question is, other than the direct benefits that is gained, are there any other benefits of a bigger Champion? To me a bigger Champion means a bigger target to aim for by enemy skillshots. 

By direct benefit I mean the skill's direct active buffs.

* Nasus Health Gain, AoE and AD increase
* Renekton Health Gain, AoE, and Fury regeneration
* Cho'gath "permanent" health gain
* Surge's AS and AP increase
* etc...
