Make Triffid Queens extremely slow

Triffid Queens not only have a strong attack but they also have an OP power of which they can grow entire forests under their feet as they chase you through town. The issue here is that they do so at a high speed, thusly making it so they can completely destroy entire towns in too short a time as an ent-like would really be able to.

Please make it so it takes triffid queens an extremely long time to move, thereby creating better balance because they can’t quickly do their thing all over the map. It would also reduce lag when around them.
