Grunt is definitely weak link in terms of micro and speed. However, he is good with execution of strategies. In scandi game he defended his base whilst taking out all enemy fish and winning land too, but you can see the lack of speed eg. vils idle after walling in wood for long time, archers dying to tc often etc. MR too he had the right idea but unfortunately was too slow at pushing the landings, also needing halen to come save him from chris landing probably cost them the game too.
