We are at a point where the discussions on a particular issue are hitting an impassible wall. Clearly, the devs are attempting to make nano pool management an important aspect of pvm and pvp. Currently it is the stark opposite, where the occasions that a profession has difficulty maintaining nano are exceedingly rare. This makes the task of concieving AO under mechanics that cause frequent and sometimes immediate loss of nano pool, and therefore a lack of casting, quite difficult. I personally have a conception of AO under a constant risk of running out of nano and having a strong dependence on professions that can replenish those pools quickly, but many would argue that it would still be far from as important as healing, tanking, damage dealing, or debuffing.
I understand the difficulty in thinking such a simple task as healing nano could be as important as healing someone's health, but I believe that nano-regain professions will be a necessity in the future. If this is a true assertion and follows what FC devs are intending, then it would help the discussions progress exceedingly well if more people could be convinced to share this perception of need.
My proposition is hopefully simple and certainly a strong one. For a period of time remove the effects of Nano Delta so that players do not naturally regain nano over time. Players would be able to use sit kits, they could use first-aid, they could perk genius or use other regen items, but natural Nano Delta regen would be gone. I believe the removal of Nano Delta for a time could adequately replicate the effects the largely increased nano costs would have in the game environment.
The aim here is not to make AO unplayable for a time. In fact, what I would expect to happen is a growing desire to invite traders, MP's, NT's, and keepers into teams. This could only be a good thing for those nano-regain professions, but at the same time a lot of players would begin to experience the uneasiness of frequently being without nano.
If making nano-regain professions pivotal to the pvp and pvm environments is your goal FC, then this is my suggestion to convey those feelings onto all players and hopefully quell the debate about how useful a profession will be.
