This game could do with public battlefield events like Walk of Echoes from 11. This may help people without active LS's find some players/new friends and lessen the LS-only events. It would also be handy if these battlefields were easier to get to. I much prefer paying gil to warp over to a zone than using anima x.x
I'd also like a twist on endgame. In 11 it was the case that endgame was just for the players. Do the NPCs have no stake or interest in the endgame? Lets use Sky as an example. If Sky was in 14, i'd like instead of competing with other players, why not compete with Garleans who are trying to farm mobs to pop an NM? or come across Garleans fighting Kirin. Why not allow us to killsteal from them or nuke their healer and watch them wipe lol. This could also be implemented as random dynamic world and wildlife events. Wouldn't it be more fun to come across a party of pirates or garleans XP'ing on mobs rather than coming across them just standing there as static spawns. Basically, turn the table around, let the players be the aggressive mobs lol. Turning the table around again, there should be random chances for parties of Garleans to spawn on your own party when fighting NMs or grinding.
Also voting for more Besieged/Campaign type events. I'd like the events to play out more like a War than an isolated Battle though. I was never fond of Campaign Battle being in just one spot really. Why not add checkpoints or something throughout the zone to keep people moving or to add objectives that change during the battle, e.g. kill all/defend npc/make it to x without dying/kill mob before it gets to x/ close city gate /open city gate/ plant bomb lol / repair gate / etc. (basically merge all the different types of Campaign Ops with Campaign Battle so there are tons of objectives and every class can contribute somewhat).
Also voting for Dynamis-3nations. Without the silly hourglass/reservation system, make it a smaller instance like dynamis-cop or make it somewhat public like Walk of Echoes. The best thing about dynamis was the strategy, it wasnt chaoatic like Besieged. That needs to be emphasised.
