You know, this may be due to inexperience (I've only played twice years ago and never as an EK), but it seems to me that I've seen a lot of posts being concerned about the ability to cast somatic spells.
Why can't we just sheathe or drop our weapon and cast the spell? The PHB says that is one thing that can be done in tandem with our movement/action. It also lists stuff like picking up a dropped axe, pulling a lever, handing an item to another character, and several other things. Now I can understand it being an issue if your AC is affected by having your weapon in hand, or you want to keep a weapon in hand in case you get an attack of opportunity (I plan to dual wield so I'll have a weapon in hand regardless), but other than that, I don't see what the problem is.
Am I missing something? Or is it that most of the people making said posts are forgetting how quickly and easily they're allowed to stow their weapons?
