1. The combat
The combat is fine. I do agree some abilities need to be pruned but they did a lot of that in shadowbringers.
2. Leveling and alts
Levelling alts in FF14 is far superior to all other mmos where your on a totally separate character, you have all your stuff from your main( like mounts and flying) and you can hand down ungodly gear if your levelling the same role. They soon will add new game + for the MSQ, side quests give fuck all XP anyway and you can do loads of other things like pvp etc.
3. Queues are ridiculous, even during the peak hours.
Just ask in novice network or talk to people and play with them , its an MMO after all.
4. Professions are done horribly
Professions in this game are amazing ! They are almost a game in themselves.
