Party play feels bad

Hi,
I decided to put my thoughts about party playing after disappointing (from this aspect) abyssal league. My dissapointment was linked especially with disabling Merit of Service shield after one week of start of the league - without any response from GGG.
I`ve played poe 1 since, idk, about 6 leagues, and at least 4 of them I was playing support role with my friend in duo. I`ve tried playing also supp role in poe2 0.2. and in comparision to poe1 - it felt much worse.

There are some points I think GGG should work on:
1. make more spirit gems with "aura" tag... there are literally only 8 of them, and withing them 3 are banner skills. So small amount of aura skills make support roles inefficient - they can boost party members in fact only through mods on scepter waepon,
2. actually this is pointless to play duo with caster carry - there are so few ways to boost their damage. On scepter there are only 2 valuable mods like "more damage" and "cast speed", but this is all your supp can give you in this circumstances. Even war banner doesn`t work with caster`s skills (giving only boost to attack damage and attack speed). If caster playing pure ES character there are also no point using Defiance Banner (it does not improve all "defences" but only evasion and armour)
3. there are in fact no ascencencie`s which can improve supp playing. Disabling Merit of Service made pointless building Warbringer to reach 75% block cap. Tactician have 10% more spirit (wow!) and in fact that`s all. Node that gives your allies 25% dmg of your main weapon dmg force you to resign of scepter... (it`s not neccessary to point out that it`s again usless for casters carry). There is an option in Chronomancer but it`s still so weak improve for party playing
4. support player don`t get any benefits from partying, as we care on developing atlass passive tree - doing corruption zones in paty member`s atlas doesn`t give points for support`s atlas passive tree. The same is in case of pinnacle bosses.

You should remember that after all POE is a MMO game, which should give lot of fun and lot of options for ppl who want to play as a party with others.

PS. sorry for my english :P I hope that most of that I wrote is understable :)
