While that may be the case, several jobs already won't gain much space even if combos where consolidated, thus any new additions come 7.0 will start pushing people towards it if implemented. A job like say, Ninja or Gunbreaker aren't saving all that much space. Which means they'll eventually be squeezed into it as new abilities are added over time. Regardless, this is more in response to people who insist if combos were consolidated, they'll suddenly add in new combos for tanks; more DPS for healers and etc. A lot of people who do ask for this often believe it'll pave the way for added depth and not simply less buttons with little else. If it actually led to depth, I'd be more open to it.
It is for PvP. If the transition were simple enough to move over, I suspect they would have done so already.First, it's not a new system. We've had it since Stormblood.
Second, so what? At worst, those who refuse to consolidate go from, say, some 24 buttons to 27. That's hardly damning to those who like their buttons or consequent finger drift.
As for caring? Well, all the people who dislike combo consolidation. I'll throw that back at you. Who cares if you find 123 pointless? At the end of the day, we're essentially arguing preference.
You neglected a third option where some jobs that are already squeezed even with combo consolidation are inevitably forced into a system they don't want because new buttons are continuously added and now there isn't a reason to prune away any. You're also assuming people are simply unaware combos aren't unique per se and just don't realize they can condensed. Most are. They simply don't like the idea.(A) jobs will get more complex and thus make the option no longer an option, or (B) that the option will remain as much an option (and simply that, with it becoming more obvious that there are no unique affordances to having those separate buttons for rigid combos, fewer people will feel inclined to favor that bit of extra memory aid over button efficiency and thereby depopularize something you prefer, even if it still remains truly an option)?
