I don't see the appeal of soul-bound gear at all, in any variation, including time-limited blessed gear or not being able to equip items looted from other people.
One of the important things in losing gear is that it keeps the economy running, allowing gatherers, refiners and crafters to keep doing their activity at any tier. Eventually, the markets will be flooded with items and the devs will have to find ways of getting rid of them faster. The most common solution in this regard, which will probably be implemented by Fractured quite early is a chance per item to get trashed when the player dies. Having accessible blessed gear means that instead of losing 3 expensive weapons and chestpieces in a big zvz, players only lose one. It just goes against the main idea of keeping the economy healthy.
PS: If the blessed gear is not accessible enough to buy it in a situation in which you'd die with expensive stuff multiple times, then there's no point in using them.
