I'm not sure why everyone is so hostile here. It's possible to talk mechanics and healing strategies without belittling someone's skill. As a shaman, my first instinct when I see someone taking damage is to throw a ward on them, then hit my group heal to replenish the whole group. That method worked great for a long time. With Pact last expansion, I changed my thinking and I started to hit single target heals more often instead. But there was a period of time while I adjusted where a heads up would have been nice. With the way Bleedthrough now works, the additional ST ward is completely ineffective if the group ward is up, so I hit Torpor or another ST heal. Bottom line, I don't mind at all when people in my group use Pact. In fact if it helps the mobs die faster, I prefer it. Is it courteous to let a shaman you are not familiar with know you are using it, since you don't know how they manage their spell rotation? Sure is. Will I figure it out fairly quickly on my own if not informed? Absolutely. Maybe it's just me, but I think so many of these type of issues can be solved if everyone makes a small effort to be kind to each other. I guess that's a step too far even in a fantasy world.
