I've been practising both the top Cancon list and top LVO list and they are both solid. In fact they are my favourites over all the lists I've tested, they stand out,but I can't decide on which for a tournament I'm going to, and list submissions in about a day.
Regarding the 3rd place cancon list, it's got so much power, and after a few games little synergies most other don't have really start to stand out. It plays like pre faq in the sense you have two major threats and maybe a weak 3rd objective screen. Whereas the LVO lists and the list I took to cancon, has 3 block of hearthguard to threaten more of the board. It's a tough one. Anyone else have thoughts on this?
