Why don't you blame the Revenant in this case? The situation is absolutely the same with him, an absolutely useless warframe in the party that does nothing but himself, yes, don’t mention the disco ball, this laughingstock does not damage sp. This frame began to appear quite often after the release of the prime version, especially on all kinds of Defenses and Interceptions. Same situation with frames like Gauss, Kullervo, Baruuk, etc.
