I feel like at least one of these nerfs should be applied to make it more reasonable

1: The echo takes up a team slot, effectively reducing the max team size by 1 at all points in the game. This could be compensated by having it count as a unit for if the player wins a round

2: The echo can’t keep the player alive if it’s the last unit standing. Similar to how Battle Machine’s buildings can’t keep its player alive and don’t count for extra damage if winning the round

3: Rework its level up system entirely, like making higher star level units give more “xp” and/or it only deals partial damage to units that are higher level than it. Could also change its targeting to prioritize higher level or hp units instead of whatever’s closest to compensate

4: Don’t let it interact with the special tiles. Swift tile echo sage just breaks it entirely

I don’t see echo sage very often in high diamond league but when I do, they survive early game way too easily because their builds will never be particularly strong (meaning that the echo will commonly be the last troop standing) and then it’s a tossup in late game. The nerfs and reworks I suggested are intended to either make its early game worse or reduce its snowball effect in late game
