First of all, thanks for your comment ; it's pleasing to have some feedback this early - it's even better when it's positive :D

Now about your suggestions :
- The main idea behind guardian angel (which comes really late in the game) is to make it risky for a team to focus you down, knowing you'll respawn a few seconds later - and most likely stun the closest target as soon as you get back on your feet.
You made some point though, because if your team is already struggling, replacing GA with a more standard defensive item (picked-up in the "situational" section) could be a better option.

About getting some more AS, well, it's not that easy since most of the time your team needs you to be tanky, and madred's costs really too much to be rushed. I would only consider a high-AS (thus less tanky) build if I had some very tanky jungler by my side ( Rammus makes a good for a "very tanky" jungler)

I'll keep these reflections on the back burner till I get some more feedback, thanks again.

Ello!

Nice guide in general, but i would never ecommend guardian angel to anyone unless they have stacks they can lose, like cho'gath. I would recommend spirit visage (for the bonus healing from hiten style and your ult), FoN (for the MRes and massive hp regen), or thornmail (for the bounceback damage.)

Wits end is an overall good item because of the AS for your hiten style.

I see you have atmas... It would be OKAY, but not amazing. I would love to see more AS from items that will help be tanky like madreds for armor.

Randuins is an excellent item that can replace GA like the above items.

Merc treads are perfect for your passive, so no complaints there.

Great build and explanations in the chapters. Keep it up! ;)
