As an introduction
Current ability: Remove this unit's Immunity until the start of your turn.
Previous ability: Remove this unit's Immunity until the end of your turn.
It may not seem much but there is a huge different there. The previous version actually had a purpose, there was a clever idea behind this ability, that of storing boost on an immune body, similar to the newly released Lonely Champion for syndicate. The current version might aswell not have an order ability, it doesn't serve any purpose and makes no sense.
Now the previous ability had some problems, hence why it was changed. First of all it was used in no-unit decks, very popular and unfun to play against, however to combat that type of playstyle a 13 unit minimum has been introduced. Another tactic that apparently some found a bit oppressive was in combination with Mystic Echo and Garrison, giving immunity to 20 points. This tactic is unusable now because mystic echo can't play garrison anymore and the bigger change is yet to come with the announcement that Mystic echo will be reworked, probably removing ST's ability to play 2 specials in the same turn, outside Forge which is limited to 5 points.
With all this in mind i think that once the leader rework patch hits, Saesenthessis should revert back to her previous version because the factors that caused her ability to change no longer exist.
