I made an equipment change on Tayrel, after which he was showing a speed of 147. When I ran my first arena battle, using High Khatun as leader, I noticed Elhain was attacking before Tayrel, which shouldn’t be the case as she has a speed of 145. I ran some tests on campaign, and when High Kahtun is not leading Tayrel attacks first, as should be the case, but when High Khatun’s aura (increase ally speed in all Battles by 19%) is active, somehow Elhain is faster... or Tayrel is slower.
