So about 2.0 and its changes to the Ceucible, here's my main takeaway:
The way we play has to change fundamentally in terms of loadout selection. Pre 2.0, most of us had a go-to weapon. If you mained Thorn or TLW or Red Death or whatever, you basically kept that 99% of the time. Your Special slot was probably always a shotgun or a sniper - maybe changing it out depending on the map.
The thing is, good weapons were far too versatile and could always be used everywhere. Now there's maps where you definitely want a Pulse Rifle, others where you might want a Scout, others where you feel a HC or AR would work better. It'll be hard to play at a high level with a single weapon trying to fit all the different maps now that damage drop off is so clearly defined for each weapon class.
This is interesting and will promote more varied play, but it'll also make it far more difficult to master a single weapon. You'll be rocking Messenger one match then switch to MIDA or Salvation State the next.
I still will wait to make a final thoughts on these changes since we haven't gotten 2.0 weapons/gears.
