personally i lean more towards sharks then i do morrsarr guards right now.
On the charge 6 Morsarr guards do a little more damage with buffs on and then they can shock people. They also still do boad control better than sharks
On the other hand 3 sharks have heir harpoons. thats 12 shots pr. turn + they are way better in close combat after the charge. I know we dont want to be in combat more than 1 turn but we have to ready for the what ifs.
i still think morrsarr are great and i will have them in armies, trying them out and learning what works better when, but right at this moment i am all about the sharks.
