People still whine about Disruptors? My God. They already got 3 nerfs. I guess you want to make them useless like the Flame Tank? It has no uses after the 3-4 nerfs it got.
RIP Flame Tank and Disruptor.
Anyways:
I kind of agree on the Artillery, because they have such a long range and they one-hit most ground units. Maybe accuracy nerf, and unable to shoot close (Juggernaut already has this).
I don't think changing the price on OP units work, because when you do finally get them out they will be just as OP anyways. So increasing the price on specific units won't balance them I think. Like say if Artillery would cost 100, it's just 10 tib more which you will harvest easily, then it's just as broken as before when it comes out.
Something needs to be done to Tick-tank, not sure what, but it's never used. Costs more then MBT, is slower and vulnerable when moving. Mobility on a tank is usually what makes it good.
Some suggestions:
Tick tank costing 70 like the other MBT. Yes it's better when still, but it's UP while moving, think it balances out pretty well. If a MBT is guarding the Tick-tank will always lose. And Nod has no healing drones to keep them alive like GDI has for their defense units like MG Squad.
Or make Tick tank faster movement speed, so they can actually get to the pads faster and dig in. Then the price of 80 is okay.
Or nerf the defense buff from 75% armor to 50 % armor, but increase the HP while moving. So it doesn't die too fast while moving and is not OP while dug in.
Hammerhead is like a flying fortress, a fat fortress, has quite a lot of HP, but too slow. Once again why Phantom kick * is that they are super fast and mostly one-hit kill all air units, good for hit and run tactics. Hammerhead? It can't chase anything and doesn't even have a good DPS. It only wins if it's defending and enemy aircraft ATTACK it. Which is very weird, who builds a Hammerhead to guard an area? You usually build it to chase down the enemy aircraft and it fails at it's job. I think speed is the key word here, increase it's speed and DPS, and maybe even lower the HP, make it able to actually chase enemy aircraft.
Oh, and Flame Tank needs some love.
Liang drone, cost 10 more, or cooldown longer. It's easily spammable and the point it's flying and can contest rocket pads makes it too mobile and cheap. I've seen countless of games won by a cheap Liang drone to contest a third pad for a steal. No other Hero powers can do this. Or make it spawn in, or come from the base, it just materializes from thin air and wins the game.
