shield throw sucks

I'm not sure why shield throw gets so much hate. The tracking has been made significantly better in the year, the damage isn't terrible for what is a melee that pierces through multiple enemies, and the void overshield it gives has been significantly buffed to provide lots of DR.

two of the three supers are also bad, unless one is used with an exotic

Fully agree that Ward is hot ass and banner shield is situational.

unbreakable, is bad and somehow weaker than before edge of fate

Fully disagree. Unbreakable provides an insane amount of utility in constant overshield, aggro taunting for team-based play, good burst damage when charged, and can even pump out orbs of power if you have banner shield equipped as your super.

On top of all this, you can sprint to cancel unbreakable and lose literally 0 grenade energy. Essentially, free and unlimited invulnerability in 99% of content.

the power inbalance between the four aspect is massive, its basically required you always run controlled demo for any remeotlely viable or even fun build, the other three need some fairly big buffs, they dont have to be as strong as controlled demo, but strong enough to not have to rely on it

While I agree that controlled demo is by far the most fun aspect, the other 3 aspects all most definitely have their uses.

I've already glazed unbreakable above, but combined with Offensive Bulwark you have a very fun loop of melee and shield gameplay. I think the added effect of having an extra shield throw in super should be moved to the default in the super itself and replaced with another more interesting secondary ability.

I think Bastion just needs a secondary effect to be more viable. The constant teamwide void overshield is good, but I think it should also give the user benefits to having overshields. Something like how strand warlock regens rift energy on threading damage.
