Someone else doing the same fight in a different way doesn't take away from your achievement in any way.
Put on your big boy pants, congratulate him too, even if he's a 'scrub who used 3 DPS & heal combo' and move on.
whats wrong with using 3 DPS and 1 healer, your own tank was in half DPS gear.
the goal was to 4 man it right? if they gets teh job done with 3 DPS and 1 healer, then why does TcMeat feel the need to defend his own acheivement?
some ppl have inferiority complex
