You can talk and quote till the cows come home and leave again, but you can't tell me that I haven't seen Ninjas grab hate more than once without voking, I have, nor that an En spell wouldn't help regardless of what level it is.
You can talk all the same, i am giving the advice for this player in the best possible manner for a party and get maximum EXP, when exp is 20,000 tnl after lvl 50ish Genkai, it really pays to do maximum because anything else can make things go wrong, and death at those lvl, exp gone is not a small slice.

En-spell can help i agree, but theres a whole lot more other stuff out there that can help much much MORE. That is why i dont recommend a RDM sub or whatever just for En-spells because there are other abilities that are far stronger than En-spells. Heck En-spells arent even required for RDM. =/

Seriously man, for all the theory and job combos you throw up here, yeah most of them are highly effective, but that doesn't mean that some other combos aren't, regardless of what you've read and wherever you've read it
Indeed i would say some combos arent so bad, but there are reasons why me, and many other people sugguest these combinations for a serious party. Because they are tried, tested and have proof they work way better than any other combination there is. Now if your joking around and wanna do whatever and not really lvl seriously, i say do what you wanna do and have fun. But i have no idea if your being serious or not(exp wise), but really i can only assume serious.

It's not always as black and white as you seem to make it out to be.
Never said that. I didnt even get that impression, i am here trying to give the best combinations of abilites/spells/bonuses/whatever of combinations of a serious exp party.

see what i wanna do is make a bazzare combo ,but a good one. i like summones there kool but i realy wanna get into the action thats why i picked rdm/war.
Its totally ok to do a bizarre combo and try to make it work and if it does, congrats. But there are reasons why i say this and this seems to work because they offer that and that. Because it maximizes their efficientcy. Would a person with the same skill lvl, and the diff combo, one different like say SMN/WAR, and one recommended like SMN/WHM, be the same? Nope...thats all.

RDM/WAR...well its ok til lvl 30..then your melee slacks no matter the sub, seriously if you want action, try maybe DRK? They have spells and attack. But RDM loses their ability to fight later as you lvl up and become essentially mages and which you should sub a mage to maximize your potential. Trust me my brother uses a RDM, he did hit ok at first, but as time went on he kept right on missing and hitting for crap 0+2 (with En), and he is a Mithra, the race with the highest DEX.

BTW SMNs are usually subbed for MP bonuses and Auto Refresh(1mp/3secs...it loses alot of value later unless you get a BRD or RDM). The trade off of this with other mage subs is that you lose alot of spells and abilities (magic attk up, and etc) that the other mage subs can offer and can help you become more versitile of a mage.

i see.... hmm..... ok then i might go smn/ninja for a while. but can i get the avatars if im lv 30 if i fight em with like lv 60-70 party members?
SMN battles are lvl 55 minimum and up to lvl 70 for Fenrir(he isnt easy i heard, alliances get wiped from this avatar), and well i am not sure if you can do it at a low lvl...but its prolly alot more hassle and hence why its recommended for high lvl people...i dunno. =/

And i wanna say, please dont go for combinations just for cool factor...look at the job and what it can do to help define your role in the party(your mainjob=your role). And i like to ask the original poster...are you really planning to try these combinations seriously or just fooling around with em?
