Not even in the same ballpark. Walter would be comparable to a completely gutted Dragoon in Aigis due to having only 6 shots.

Aigis was just barely hitting the cusp of ridiculous powercreep now that I look at that time period. The biggest powercreep they had at that time was the Chef class which I can't imagine AK getting without it being nerfed to the ground. Imagine a melee unit that when placed on the field causes all your other melee units to gain up to +3000 max HP and +1500 attack/defense. As well as a supporter that gives allies in range +120% SP recovery passively.

The big paradigm shift for Aigis occurred after their 7th Anniversary with Arge.
Imagine a Liberator that could still block and hit things not during skill, but grew up to 10k+ damage and did true damage during skill. Nowadays she's pretty mid and a copy of her is literally a summon token for a different unit.
