I would very much like to see it be easier to play as an animator build. As it stands now there is no way to protect yourself from being found out other than being able to -ward or to just not summon your creatures period. I feel there needs to be a change of some type that makes our lives slightly easier. A simple level 1 Alarm spell would work wonders or even the level 2 Silent Alarm, these would give a cue of some kind to the caster that someone has crossed over the wards...allowing one to place them at transitions to know if you're about to be made so you can unsummon. These spells would also add another level of depth to RP in many other scenarios as well.....this is just one example of something that could make a necromancer's life easier and more enjoyable to RP on the server.
A level 30 wizard would very much be able to polymorph their undead to look as another creature, this could also be a slight solution but give them a sort of disguise/spot check just as normal disguises work....just throwing some ideas out there. I could make this a lot better but sleep is needed and it gets the idea across.
