The changes I would like to see are below.
1) Reduction in the amount of stacks lost on Cho'gath's ult when he dies.
2) An increase in how quickly Heimerdinger is granted turrets.
3) Balance champion abilities that scale off minion kills (Examples: Veigar's Q, Nasus' Q, Sion's E)
4) Ziliean is the only character that does not have a passive for Dominion. I know the XP bonus would be too OP, perhaps something more balanced such as (reduces time zilean and his allies spend dead by 10%) That still meshes well with his master of time theme and gives him a global passive on par with other champions.

Can we work on capture points soon?

I tried Zed on the PBE on Dom in a 1v1, and over all I like the energy regen increase. I notice it.

i'm loving these changes especially the energy regen and removal of global penetration

i still dont like how Garen's passive is affected by the heal nerf do

A better fix for Shyvana's Rage generation would be not to tie it to relics, but to tie it to CDR. 1% increased rage generation per 1% CDR. Similar fix could also be applied to rumble, make his skills generate a % less heat based on CDR so he can cast spells for longer.

Mastering heat control? Since when has it been more effective to stay in the danger zone than to just spam all his abilities as fast as you can? Definitely not since they nerfed the bonus he gets from danger zone.

respawn timers too please!

Nome, how inclined are you with making individual champion augmentation when it comes to dominion? e.g. Nami no longer stops when caster spells.

Nome, how do you feel about making Tear a constant charge time like RoA? Right now, it's only chargeable on a small subset of champions who have mana toggles or 2s CD spells, and if it was made possible for normal champion to charge it, it would charge superfast on those. There's also the issue of if it had a low cap to charge, then it would be harder to use the item evolutions properly.

Edit: After some discussion, the idea proposed is this:

Tear stays the same. Charge system yadayada.

Manamune and possibly Archangels have the charge system replaced with flat mana gain over time (however much makes sense). This means you need to sink gold for having reliable fast charge time on champs that can't charge it, so it's not totally broken "spend 700g to get free mana, 1400 more to get dumb damage whenever".
