If you die because a lack of front stun immunity you just didn't plan well. You are so much more likely to die from a NPC spell or having it fail on you. I remember being more frustrated at rezzing in gigantic or burning through shrink potions with my fatty.
A SK can solo without getting hit much if at all. A SK can tank while being chain-stunned due to spell aggro. Stats, slam, FSE are all handy as is the Iksar/Troll regen...it's just not a deal breaker.
The racial advantage may edge out a raiding guilds warrior tank order but it's a slim one. Seniority and HP's likely would play a bigger role in the decision on who to start with.
As with everything you gotta pick what you will want to look at constantly. I just wish gnome SK's were a thing because they were the best.
