more events for the casual player
Casual players have a bit to play with now, I think they should be satisfied. Really, the only thing you need for solo content is viable experience and SE has been working on that quite a bit. Solo content doesn't need elite gear primarily because if it's solo, anyone can do and it's no longer elite.
more event for hardcore players
This. Needs more, but SE already said they are working on end game content for WotG so I can't really say much about it.
update to PvP system "Conflic"
Stan said it best, add more reward and people would consider it more.
jobs update and battle balance
I like this, but not usually the way SE describes it. lolmeleemage.
update the crafting system , H.E.L.M.Chocobo Digging , Clamming and Gardening
The only ways to make these types of farming more appealing is to add more synth items or better yet, consumable synth items. Fishing and cooking are constant great sources of income based entirely on the fact that there is a never ending demand for food, but most other crafts are not as fortunate. The demand is basically non-existant for a lot of materials obtained by HELM. Add more consumables like High Breath Mantle except a bit more useful (better stats that don't wear when removed).
update the old events and battles (Dynamis ,Limbus)
If we cannot make dynamis instanced, instead shorten it and increase drop rates to account for less farming time. It's already such a tedious, boring event that lasts 3-4 hours, remove the headache of such a long event while at the same time, decongesting the bottle neck it causes.
Add instances to Limbus and add more uses for Ancient Beastcoins. By the time a single player obtains full Homam which a good majority of people seek, you have enough coins for pretty much all the items you can obtain and more AF+1 than you can get upgrades for.
new BCNM , KSNM , ISNM , ENM
We have them, it's called SCNM.
update sky and sea
I wouldn't mind this. There are a ton of unused areas in sky and several telepads which lay dormant.
update the HNM kings , Wyrms and Toau
Add drops to wyrms: Tiamat is the only one with a worthwhile job and it's just one item for only 4-5 jobs. The other two stay up unclaimed 24/7 which is really kind of sad.
Same thing with ToAU HNMs. Add drops that actually get people excited about and screw the need for Mythic weapons, 99% of the player base does not have 90 mil even though they delude themselves into thinking it's anything more than a pipe dream.
Increase the difficulty in Kings and kill the bots. And for once, remove any and all items that are profitted from cheating as a warning to all players. Nothing worse then seeing a LS bot while players refuse to acknowledge it because they stand to gain from it. It's one thing to plead ignorance, another to feign it.
