Skill Points and EXP values are way too low.
Ok so I really want to give FFXIV a good play through and another chance, so I decided to log in today and level my character some. Here is my experience.
I pulled 4 guild leve quests. 3 in Nanawa Mines and 1 in Nophica's Wells. All 4 guild levels were done under guardians favor for increased skill.
My character is a rank 28 Gladiator I started out with 23815 / 33000 Gladiator skill points and Physical level 31, 72940 / 160000 exp.
Upon completion of these 4 guild leves I was then at
25510 / 33000 Gladiator Skill Points, net gain 1695 / 5% of my current rank gained
75879 / 160000 Experience points, net gain 2939 / 1.8% of my total level gained
Completion time 1 hour, 30 min.
1695 skill points and 2939 exp for 1.5 hours worth of work is way too low. Its disheartening for many players who make it past level 20 to get so little accomplished when they try to log in do some guild leves and are left with a sense of frustration about getting so little accomplished. 1.5 hours is a long time and to only get 5% of my level done it just makes me not want to log in.
The exp curve seemed fine up to 20 but past that it jumps a lot almost to the point where it requires so much time and grind that it becomes unfun and a chore to level.
One of the biggest problems with FFXIV is how high the leveling curve is, if players feel like they aren't accomplishing anything they won't want to log in or play the game.
Suggestions:
First off I would lower the EXP needed to level 1-20 felt about right with the time it took to get each level. Levels 21+ need to be lower exp needed to level. On top of that each time you complete a guild leve quest you should be rewarded with 5% of the total skill points and exp you need at your current level, along with some equipment and gil. It is very common for other MMOs to reward players with Exp when they finish a quest. It is very reasonable to do about 20 quests per level. The rate I am seeing ingame at the moment is about 80 guild leves to level at level 28.
