So i was reading a bue-tracked thread about Lightwell usage were said blue-poster argued players have to get used to using lightwell like they got used to summoning healthstones or mage cookies.
This has me thinking... maybe there would be more awareness about the use of lightwell if it was relying on some "teamwork" to bring to the battlefield.
A simple channeled summoning requiring all group to clic the summoning portal before the lightwell can be droped would raise "symbolical value" (wow, we need 5 people to bring this out, must be important) of the well. A more coercitive option would be that only those that helped bring the well could recieve it's healing...
Of course this means it would be difficult to renew during a fight but duration/charges/health could be tweaked accordingly.
