Sync doesnt work very well right now. Otherwise we wouldnt have Unreal version of old primal fights. When you look at the good old Crystal Tower raids, you can skip almost every mechanic, because everyone is overgeared and have much better stats than 6 years ago. And with each expansion, we re getting stronger and we will burn old 24-man raids and 50/60/70-dungeons even faster.
Then, it gets pretty boring to run dungeons without any AoEs (Level 15 MNK for example). Its far away from being fun, if you re not able to play your class at its full potential (MCH 50 for example). With each new expansion old (low level) skills will be removed or replaced. That means, with each new expansion, you will lose skills on level 50. Needless to say, the job/class will get its full potential on max level. You dont need to start learning your class before reaching max level. During the level phase, your rotations will change from time to time.
But lets break it down:
1. Sync enemies UP would not solve problems
You cant just sync enemies up to 80 or something else, when you have huge differences between character levels in your group. A level 80 healer would be the new tank, while the fresh 20 gladiator cant learn/do his job properly.
2. Having the full set of skills
I really like that idea. It shouldnt be that hard to make it possible, but I have no idea how to balance that. Are we really stronger, just because we having more skills? Or is it enough to just scale down our stats properly?
3. Better sync
Sync just scales down the main stats (for the most part). But since our ilvl is pretty high, we re still extremely powerfull. At some point, I kinda miss the challenge and feel of older fights. Since we can skip important mechanics, people wont learn anything that and dont need to put any effort in it. When we want to have sync working better, the min ilvl option must be added. But do we really want that? To be honest here, I dont want to spent 60 mins in ancient labyrinth, because people forgot how to play it.
4. People dont learn
A hard topic. When it comes to my humble opinion, I would remove leveling completely. Dont start to "learn" you class with 50, 60 or 70. With max level, you have all the tools you need and can learn rotations properly. Also, the time needed for leveling a class from 50 to 80 (MCH, AST?) takes more than 30 hours. FFXIV is no rocket science, so who really needs more than 30 hours to learn a class? I just look at it, read the skills and doing some practise on the dummy. 1 hour max. The overall leveling process is not about learning. Its about to get players busy for a while. A old system ANY MMORPG haves.
In conclusion: I would like to have at least my full set of skills (like in PotD back then or Bozja). I would appreciate a rework of the sync-feature, so people dont get stronger with each expansion. Maybe adding a special mode with better rewards when doing old content sync and with min ilvl. I still dont see the value of having a leveling phase, but thats just me.
