I agree partially. Dreamkazper, Fischer, and Gamsu are all stellar pickups, but I think Kyb and Mistakes are both mistakes (no pun intended.) Yes, Mistakes is a great tracer, but I feel his lack of flexibility will only detriment the team. He could of course be just a bench warmer who would pop in for tracer based comps, but I think Boston would be more successful if they found a suitable hitscan DPS who could also play a strong tracer. Good tracers are key, but not every team needs a sinatraa or an Effect to win.
Meanwhile, Kyb's offtank play has never impressed. On a note of Snow and NotE (haHAa), they're both relatively unproven and largely inexperienced (at least in the tier 1 tournament scene) tournament players, and they're truly only on the rumored roster because of their relation with HuK.
If the team can find another strong DPS player, a couple reliable offtanks, and a stronger support core, forming a team around Dreamkazper and Gamsu specifically could be extremely viable.
I'd love to see Architect come in to be a straight projectile DPS player that not only can mesh with Dreamkazper's DPS flexibility, but also refuel the already existing chemistry between him and his old tank teammate. Even adding in Twilight and making a mini-conbox within Boston would be a smart move.
