How would you feel about end-game gear only being useful for 3 months?

[Jennestia]

I like that gear will need to be continually upgraded. For those who don't, since I don't really want to read through the last 30 pages what would you prefer?

A. No new gear is added
B. New gear is added but is worse than that currently available.

See this is where most "yeah I'm all for throwing my gear away every update!" people are confused -- It doesn't mean new gear won't be added, it means gear will be added that doesn't throw your previous accomplishments away but instead something new to work for, in other words, your last set of gear will be useful just as well as the new set of gear you're working for.

Making content that people will repeat needs to have a reason to repeat it to encourage people to continue to play, this means that there needs to a reward for doing so. If that reward is worthless to you, what is there to keep you playing?

I ask you the same question:

If you know doing Valberd's Dungeon will produce great gear that will become useless the next update (which could happen as little as a month away) then Hyzonia's Dungeon produces even better gear but will become useless in 2 months...why would you play? Why would you do things that will be utterly pointless in the grand scheme of things?
