Question about 15k Druid armor update.

I know that in the future, the 15k Druid's armor sets will get its new look. Question is, if I currently have the 15k Druid's armor sets, will it get the new look when the update comes or do I have to buy another set just to get that updated art for Druid's armor sets?

It's a question that nobody knows the answer to accept ANet, and they haven't said. In the past when changes have been done to artwork, old artwork hasn't always changed (see old runes vs new runes). Only time will tell. If you're worried about it, hold onto your $$$ until things change.

I agree. Since theres no point in buying it now, don't bother taking the chance that it won't be changed later.
