Guild Wars is easier using this strategy, try it and good luck!
Ice Demon Method - Guild Wars
I think it's more of pd method than ice demon.... And the video is a raid, not gw. Makes more sense if u record a gw run with this strat? Looks fun, but extremely hard to find a gw base to try it on.
Personally I don think think this strategy works 9/10 'gw' base. Most people have arrow towers and minimum lvl 5 green garrison. pd at lvl 1 will not survive long enough to stack, not to mention an ice demon.
I used this in GW, was lucky enough to find a base with troops out.
It works well but a non evo pd and an ice demon at high level works better.
You could stack a non evo low level pd on an army camp or heroes altar outside the base with doing minimal damage and continually stacking.
It will work, will just take the right base to do it with
