I think Turner was our natural dynamic go-getter of a leader, unfortunately. Khezzik has no desire or ability to lead, Nirion lacks confidence and experience, Tonik seems content to see where things go and fiddle with stuff along the way. That leaves Takeshi, who is also the oldest and the most powerful mage, and has previously placed himself in the role of mentor and teacher, as the best fit for leader.
If Gladr is okay to take that on, and can work around the issue of not particularly wanting to return to Waterdeep, then I'm happy with that. Otherwise, I'd be fine with adding another player, or some light railroading.
(I would be happy to post more, but in the current situation Khezzik doesn't have much to say, especially in front of the dwarves. I check in multiple times a day and I'll let you know if I won't be around, so if I'm not posting it's because I have nothing to add. I wish we had a little "like" button or some indication of who has read each post!)
