Guild Wars 2 Silenced Assassins

When I used to pug up with guilds on SBI's TS, the water numbers were always assigned for each of the elementalists, not the type of fields that they used. That way they had a for sure way of knowing that water fields wouldn't drop on other water fields, which of course is pointless. And then if one ele couldn't get their water attunement out for whatever reason, they would say it's on cooldown, so the driver could ask for the next elementalist's water. It's the same thing you already do for veils.

Also, are you sure you want me to put out one field out a few seconds right after the other? It seems like keeping one of the water fields would be more effective for more frequent powerful heals, since blast skills aren't going to immediately recharge.
