I was thinking about, how In my opinion, some degree of limitations needed to come into play so that we are all not uber gods. Now, I am not saying that people shouldn't be able to master everything. However, I would like to see some kind of limitation in the field. Someone else has suggested maybe setting a "main" at your "mog". So this way you don't have to worry about a seesaw effect. What you earn you keep, but it also keeps us all from being uber jobs. I do not have the perfect answer, and I am sure that there are those that want no restriction. You are entitled to your wrong opinion (lol, jk sorta).
Anyways, I just thought of not necssarily a solution, but a thought that came out of my ponderings. How will abilities and spells that are not a 1-time and instant function be handled? I mean things like protect, regen, bio, haste, last resort, boost, sharpshot...... you get the idea. What I am getting at, is if you use these things will/should they keep in place once you switch jobs?
Here is an example (ignore the ffxi jobs and abilities, as these are just for reference): I am a Ninja, I switch to bard >>> double march >>> switch to red mage >>> haste >>> switch to Samurai >>> Hasso >>> and back to Nin where I remain with all the benefits I just gave myself. As a ninja, I would probably be overjoyed. However, does this not seem a bit over-powered to be able to take all the benefits you want from other jobs and apply it to one? While this is not a level or seesaw limitation, it could act as a more natural limitation. It makes sense that you can only do certain things with certain jobs.
On th other hand I kind of love the idea, provided there are limitations. Like maybe if I use haste then switch back to nin, it is only half the speed, because I changed jobs. Again, I don't have a perfect solution. But let me ask this question, what is the point of having different weapons if they can all have the same benefits? If I am dragoon, but I can borrow all the powers of all other melee jobs (particularly drk, sam, and war) at the same time. Then everyone will be doing it, and there will be less job orignality. It would basically come down to a difference in your weapon only. So what then? I can be a swordsma, spearman, katana user, axeman, etc, etc., but other than that all the ,melee will kinda be clones of eachother. These are just examples. Maybe it will all work out better than I imagine, but if there are no limitations set in place at all........ I seriously doubt it.
