Just as stated in the title. With the new system, players should have access to CP build slots similar to outfit slots. At the very least, players will still need to spend gold to refine and tweak their CP builds. Even if we were charged the same 3000 gold to switch using one button, that would be fine just as long as we are not required to reallocate all the points for a needed role or playstyle for the day. If we want to play as a tank, then we should just need to change our gear and then switch CP build with one button. Streamline the experience for players by removing the unnecessary busy work of basically rebuilding our CP setup if we want to change class role for something specific. We would need at least 4 slots per character to accommodate tanking, healing, DPS, and PvP builds. There should be a starter build for each category for new players to choose from in order to provide a starting jump point to start from for said new players after reaching one of the major CP plateaus.
On a side note, the new CP system, while well thought out seems like it will be needlessly convoluted for new players and at the same time very limiting for experienced players. 12 slottable "effects/procs" with a slew of stat based boosts. On the surface there seems like a lot of options but in reality those many options will be whittled away very quickly down to the "ideal" point allotments for each role. The best analogy I can think of is that it will be very similar to choosing classes for a college degree program. Once the player-base at large gets ahold of the new system, there will be a core list of CP choices taken, followed by those taken for each role (tanking, healing, DPS, and PvP) and then you will be left with a few 'electives' to choose from. At least that is my impression from playing around with it on the PTS.
I would rather be playing the game.
