It is a big jump in difficulty. You got mostly no visual yellow markers and need to pay attention to the area, boss position / stance and so one in Savage levels. Instead of queuing, you should use Party Finder for that. It doesnt hurt to lookup guides, if you do it without a static. Also some statics also do that, instead of learning by trying.
Too be fair. We all now what kind of a trainwreck the ffxiv source code probably is, thanks to the 1.0 -> 2.0 recode. Your point still stands tho
