The lack of Link Suggest definitely slows editing down, but I must say 9and will say in my own comment, probably) that it was the 2017/UCP editor itself that made for an extremely torpid editing experience. There was constant feedback lag for what I was typing--having to wait over a minute for what I was typing to appear on screen--and even delays when scrolling up/down.

Using the 2010 editor on my UCP-migrated wiki thus far has been a miraculously faster experience by comparison. Link Suggest's absence will still be sorely missed for the time being and hinder the process, but my main advice should your wiki migrate within the next few months is switch to the 2010 editor. Long articles have been dreadful to engage with otherwise.
