By numbers I generally meant the movement speed buff on Q and the health scaling on ult.

Generally you want to limit movement speed buffs to ~50% and health scalings to around ~6%, especially on tanks. This is because tanks, well, they're tanks. They're supposed to stick to the enemy team's main damage source, disrupt them and maybe even endanger them. This however, should never mean that tanks are champions who are allowed to do stupid things such as dive an enemy adc under turret and still reck him/her just because of his/her massive healthpool and absurdly high hp scalings.

I agree that %hp scalings are a nice way to spice things up for tanks, but a 10% scaling on an ability that already has 550 base damage is too high.
