Oh I play this build quite often! I find that build works better with valk ammy + rage runes myself, and scepter/shield over hammer for a consistent range weapon set and to take the trait for more cleanse on f2 which helps gives extra team support too. Anyway, marauder ammy or valk ammy that build exists as a rather tanky dps that still does insane burst (hammer/gs) or tanky consistent damage (scepter/shield) but it does have some faults, some of which are the reliance on retal , highly telegraphed damage in the form of GS 2 or hammer 2 and no easy way to escape fights unless you have line of sight - quite often I engage fights then can't escape to reset when the fight starts going south. I think the build is definitely quite easy to play and is very strong with not too much effort, but it's effectiveness really goes down against stronger players.
