Skill-assigners are supported but De-assigners are not. Is there a reason for this? Are you considering supporting de-assigners? (or other such objects like - neutralizer)
The 12.14 new objects were considered for inclusion in SuperLemmix, and the following was decided:
Skill Assigner - This has been added, and is capable of assigning other skills as well as the permaskill set - namely Jumper, Ballooner, Blocker, Walker, Grenader, Laserer, Spearer and Cloner. Other skills were considered as well, but it doesn't really make sense for a static skill assigner to assign Bashers, Builders, etc. because the lemming makes changes to the surrounding terrain immediately (Laserer is a bit of an odd case but was ultimately accepted because well, why not).
Skill De-Assigner - It was decided not to include this in SuperLemmix as it adds unnecessary complexity to the skill mechanics, which is something I'd prefer to avoid. If enough users want it in, we can possibly add it at a later date, but I'd have to see better reasons than 'existing content support' (ideally).
De-Neutralizer - This has been added as 'Normalizer' and is identical to its NL counterpart; SuperLemmix will treat a designated 'De-Neutralizer' object as a 'Normalizer' accordingly.
Neutralizer - It was decided not to include this for reasons similar to the Skill De-Assigner. A Neutralizer is something of a 'soft trap' - it doesn't remove the lemming altogether, but is still best avoided; the complexity it adds isn't worth the relatively small feature gain. Again though, if enough users want to see it in SuperLemmix, we can possibly look at adding it at a later date.
Discussion is welcome, I can generally be persuaded. Input from users is likely to result in change. Silence is not.
