1- first thing first if ppl rank 31-39 would be moved into t2-t3 sc there would be no gear gap cuz if you remeber bolster has been introduced for this you can tune bolster more than proportionaly to reach rank 40 for low level ppl and progressly lower it when at rank 36-39 to have no bonus but jsut remove malus vs rank 40 bolstered.
2-there is not a tactic slot in 31-39 so max tactic avaible in t2-t3 sc is still 2 at same time.
3-same as above for morales
4-same for all class deifining skill , those of t4 are unlocked at rank 40 or max at 39.
4-it's not a hit at all , what about ppl after t1 being forced to play into t2-t3-t4 mega bracket? it's just better that way there is no hit , thats the only way.
5-generally the majority of fresh t4 player are totally noob that dont even know the gear and get the good gear after made rank 40 so ppl outgearing others is simply not true. Also the only easy gear for rank 31-39 is ruin; ruin is a gear which require farm pve, farm pve leave you behind in renown so it dosent really matter what you do t2-t3 with a fine bolster will always be a fun place. Also ppl will start get a hard lfie earlier, t1 time end when you level to rank 17 ppl shoudl get used to have deal with ppl more knowledge in game than em, this is propedeutic to make em improve in the game.
this worked pretty well in live with the only exeption of twinks made by blocking yoru expirience THAT was what ruined t2-t3 mega bracket in rvr and sc. Also live sc was even higher it reached a lot more ranks then what ppl would like here.
i also wanna point out that sc became few played because all the interest has been moved onto pve or rvr. You made sc going like thare are now, dev team introduced the poison, if you reall wanted to remove group queu from pug sc you could had jsut done that AND NOT REMOVE CARROT TO QUEUE FOR SC or made those carrots unreachable.
if you have problem how premade deal with pug it's another matter on how poorly sc are queued sy...
