Okay so, I know this is old news at this point but all the threads are either locked, archived or buried. So, revisiting this!
WHY is it that Level Sync has to take away all your skills? It's the only real gripe I've have about FFXIV as a whole. Losing skills to do older content/fates is just not fun. I don't see why we have to lose everything to go back.
Honestly, I feel like this system needs a revisit for the next expansion. It shouldn't be necessary anymore, especially not with people trying to play catch up. Who cares if your newer skills have incredible potencies not designed for older dungeons/trials/fates? If we're leveling new jobs and have to periodically get gimped to lower levels, we should be allowed to use our more powerful skills to get the job done faster. It's plenty tedious in the first place. It should only be a stat squish at this point.
I know it's not a popular opinion, but you have to look at it from the perspective of "Next expansion the level cap will be 100. It will take THAT MUCH longer to get there if you start a new job at level 1." Enough's enough now. lol it's time to update the older systems in this game to be less annoying. Speaking of which, older relic grinds, but that'll be another post.
The hardest part is getting to within 10 levels of the current cap. It's soul-sapping to do roulettes and be stuck in old dungeons/raids "at the speed limit". Shouldn't be a roadblock we should have to contend with while trying to gain XP in larger quantities at this stage in the game's life.
