Start in May then. It would be your choice to fall behind by waiting. Complaining about that is looking to be aggrieved.
Not to mention you are falling behind in something that you think has no value so what is the complaint about?
What if you are on a break, are temporarily short of cash, missed the notice or just start playing the game after june? Forever behind. I don't see the benefit in such a system.
Yes, as I have pointed out a few times now the bonuses are indeed very bad month to month and a major factor for that is the rolling scheduel aspect of the system.
A far better system would be something like this.
Every month you sub you get an additional +1% VIP XP bonus (max +20 additonal)
Every 6 month you sub you get a +1% bonus to named loot drops (max +5%)
Every 12 months you sub you get +1 free chest reroll (max +2)
Every 10 months you sub your VIP DDO point bonus increases by 100 (max +300)
Every x month you access a new tier of cosmetics/mounts
If you unsub you lose access to your bonuses and freeze your progression.
That way VIP would get a ton of value, long term VIP would get even more bonuses and new players would reliably be able to catch up.
