People should always be able to play in a way they have fun. good game designers know this and design the game to facilitate it as much as possible. Bad ones try and force the players to play how they think the game should be played- as we see in a certain other super hero game today.
That said if you need help making influence I can tell you how I've made a few hundred million at least. buy enhancement boosters with merits they sell for over a million each. with 100 merits you can make 20M or more, 300 merits can make you 60-70M (I'm bad at math ok but its an estimate)
Merits are made by running TFs, Doing Hamidon raids, getting certain badges, you can even convert empyrian merits into reward merits too.
