Eso Plus has been improve from time to time. The craft bag and special discount for crown items are nice touch for the subscription. However, the subscription should provide more enganging activities with the payers.
Took Fortnite as an example, they offer the most attractive subscription plan for their customers. It can be seen successfulless through their money making ability.
They setup a time limited challenge for subscripted player. The non subscripted player can purchase their item directly.
Eso should take reference from fortnite. Providing weekly/ monthly challenges for subscripted player. And also offer an alternative methods for those who has not subscripted.
This helps improving the benefit from subscripting membership. It also adds more reason for player to subscript.
For example, eso can set 4 different ways to complete the challenge (small Pve, big Pve, small Pvp and big Pvp)
Finished 5 dungeons and 1 vet in a week.
Finished 2 trials in a week.
Finished 5 battleground and 1 win in a week.
Captured 5 resources and 1 keep in a week.
Task should not be too hard but challenging enough for casual player.
With regards the rewards, they can be custome, motif, toys, crowns, lootbox, you name it. This make the subscription more engaging, compared to only passive benefit.
Items can also be purchased through direct crown coin payment. For those who do not have time and subscription during the activities.
Or here's another: ESO+ subscribers that resub for another 3/6/12 months get crown crates equal the number of subbed months. So 3 months gets you 3 crates, 6 month = 6 crates, 12 months = 12 crates. And these crates would be special ESO+ crates. Meaning, higher chance of good drops.
This promotes crown crates and incentives players to resub.
