Thank you !

Passive and Ult do NOT stack, using one of them puts other ability on CD. So you either start with passive (Goes on cooldown) and after a few seconds  (after 14 - 8 seconds)  you use R to execute enemy, or you instantly use R (Goes on 80/75/70 seconds cooldown) but passive goes on CD (14-8) with R  as well. This would prevent Cho'Gath from doing too much burst damage in % true damage. Passive is like a mini Ult now.

Cho'Gath is old champion and RIOT used to give Tanks high base damages (around 300 and more - old Sion's Q) and AP ratios (100% AP) to ensure that if you buy 5 tank items and 1 AP item, it is enough to boost your damage. But after certain amount of time, people started to build those tanks as full-AP burst mages (Old Sion did around 300 + 300 + 200% AP with Q and W almost instantly - no counterplay, plus Q had 2 seconds long stun). After that, every new tank (or rework) in the game had 40%, 50% AP ratios outside of R. Gragas was also used as AP mage in mid-lane, but after rework, they made him more of a tank with % damage and less AP ratios = people play him as a tank with max. 1 AP item (in jungle) but he can still be built as burst-mage (but not as good as before). I did the same to Cho'Gath. RoA would be still no.1 and core item, and then going full tank or 1 more AP item with resistances.

 Q's   dash is a bit slower than usual (he runs - charges - at enemies rather slowly than Shen does) so without enemies being CCed before dash, you will mostly use it as mobility, not damage tool (it can be dodged). And hitting 2nd part of Q is possible only if you are facing terrain (within 550 range) or close to towers, so 100% AP will happen only once every 4th cast if lucky. It just rewards fighting in the jungle or close to towers, baron's and dragon's pit.

Overall, there will be Tank Update (like assassins) and my goal is to make Tanks do less damage to ADCs and APCs, but have more CC, Peel and damage against enemies with higher HP. Cho'Gath's role with these % true damages would be a Tank Buster.
