I think I disagree. If I'm a brand new player, I'm still 100% going to get cls before revan or jtr.
Why is this?
You can't start farming fleet until at least level 60. And even then, fleet 4e is probably not accessible until you are pushing level 85. You can't start farming mission until you are level 84 I believe.
By level 60, you should have Phoenix (for ep/thrawn), sth, Leia, old Ben, and farmboi Luke at a much higher star count that any or toons. But what or toon will you have as far as any of those? Clearly none of the single hard node farms. You might be lucky to have even unlocked them. R2d2 is the easiest legendary to get because he follows the natural progression of the early game. And because OR has no synergy, they aren't a great early team, unlike Phoenix or Solo toons, so it will be hard to get high in arena with just them.
Revan vs JTR is more debatable. Finn and scavy Rey are easier to get than probably any revan toon. The farm for mission is just as painful as the veteran farm, and t3 is only a few days shorter. So, is 3 hard node farms easier than 2/3 early cantina (kru/kylo/fox) gw farm (phasma), 2hard node+fleet(fotfp), and cantina store (foo)? I easily 7* the bb8 event with kru/kylo/phasma/fotfp/foo and found those farms incredibly easy (probably got fotfp in a little over a months time). Plus, you can really benefit from fotfp and KRU to get you to unlock those fleet battles... So, yes, on face value 9 is more than 5 and this is harder to directly unlock jtr, but if you think of the indirect costs to even get you to farm the revan characters (ie, the investment in ships to get you to 4-e hard on farm to farm Jolee) then I may argue jtr which isn't gated behind ships, is still overall easier
