I would disagree...
Terminus was not as strong to deal with dynamically at a master level compared to commons.
When a pocket the torvald meta was formed, it became a dominant strat vs people who had no idea how to deal with it at the top level.
On launch term had some level of overtoned values yes, like the primary into altfire wombo on top of massive HP, overly long duration on shield, enough to be considerably unfair in a 100% vs 100% HP trade.
Now his dps and trade time are better, not perfect mind you, but he has the ability to move with much better cards to work around.
But dynamically, it was not game braking compared to torv rendering multiple formats of shield abilities useless with little skill or counterplay making player in your team liabilities for your success.
I never found terminus design to be an issue, I just wish damage champions had good design to deal with frontal shield pressure... something thats expected on the frontline. If the game had more options for ground based damage, deployable crossfire and better lockdown, term would not be an issue, its just the design of certain champions who favour direct damage suffer compared to his kit.
Comparing the two is not the same.
Recharge with siphon was too much.
Torv earnt a 80% winrate in PPL during that 6-5K nerfed to 2K shield HP, mainly due to the threat he created on the frontlines as the combination of shield rip, mobility hinderance and reset from team elim, made abilities strong enough that you wouldn't need a damage to deal with the defence class, you can play defence class and disable with the core of the shield defence design classes.
The particular PPL I have in mind was cheese, watching Torv just sit in bunker, waiting for enemy shields and pocketing allies, earning something like a 80% WR, while post game battle math would show he had only dealt low damage at pro level, due to the strength of his pocket in co op play, his kit not needing to deal damage to secure victory considering the strength of two shield busters and the 2k for 2s ally shield offering pretty much damage immunity to squishies vs low dps tanks. This was not very fun to fight against.
In comparason to the %80 WR torv in PPL, Terminus only reached around 70% win rate in casual, not pro league unless you talk about certain maps. In commons, you would expect the common design to be countered by something that opposes it, and a frontline version of reversal with a hefty duration would eat into a lot of the uninspired common direct damage campions who are countered by a frontal shield...
I don't think it was much of a rework compared to grovers whole kit, which was needed becase he was not actually a support when he was more frontline/flank to a much slower cast of characters.
I enjoy playing torvald more post rework, but know full well that he is underperforming by a couple tiers unless one uses a damn good nullify build.
Personally he needs tweaks to his shield, recharging out of combat, overcharging and dissipating over time while over max.
Recharge needs base speed amp for mobility.
And something to give his ult some more situational viability.
