State of mages in arams?

I know not all mages are equal in power, but do you guys think mages in general are too strong or too weak in arams?

Me personally, I find that adcs, assassins, bruisers are much more powerful and dominating over mages. All three classes have constant damage on their auto attacks and some with their abilities. Auto attacks not costing mana. Bruisers having more health so they can take a beating or tank a bit of damage while still dishing out damage.

Everytime I get mages on my team, they are always in the back doing nothing during their cooldowns or when having no mana. I get that their auto attacks are not as significant and I'm not blaming them why they are just sitting in the back running up and down because they cannot make significant help during an all out fight. But I just feel like mages are underwhelming at least in arams.

Both assassin and mage have burst but after mage is out of mana or on cooldown, the assassin wins in dishing out more damage. The adcs can constantly attack. bruisers can just keep on fighting as they tank and do damage. Mages just sit in the back because they are oom or on cooldown. Always feels bad when you see a fight finish and this mage is in the back full hp cuz they are out of mana or waiting for cooldowns and everyone is dead.
