Question about PVE & Certain Mechanics

Hello all

I've been wondering since many game mechanics have been added to the game (e.g. Siphon, Investigation and other individual character mechanics like Impetious for JKCK) I've noticed certain discrepancies in the PvE setting where there is more than 1 battle in a single event. For simple purpose I'm referring rot ROTE where CMs or SMs have Battle 1 and Battle 2.

For various team-orientated or individual ability stacks: SLKR, Dr Aphra and other Siphon stacking toons lose all their Siphon stacks as they finish the first battle and must stacking again in the second fight and that doesn't make any sense to me >< besides for GLs like SLKR I can't say I'm able to use other character Siphon abilities many times in one single fight I've noticed this in particular for Aphra and Inquisitor Bariss, usually I can use their Siphon once per battle, for Aphra that usually happens at 0 or 10 Siphon stacks because of Ig-90s addition to the team. 

-> is this working as intended? It's quite a big nerf to various teams and characters, GLs don't feel it as much as non-GLs because of the speed difference 

Then you have the various character or faction specific mechanics that behave differently, for the Mercenary "Soldier of Fortune", I admit I don't know what happens there but I've noticed these things:

1. Lord Vader and Underestimated stacks continue from the first to second battle uninterrupted so you continue to gain stacks.
2. Jedi Knight Cal Kestis and Impetious stacks behave differently: if you end battle 1 of 2 with 20 Impetious stacks on JKCK you start the 2nd battle with 0 stacks and just the chosen configuration at the end of the first battle.
3. Darth Vader's (Duels End) and Vengeance stacks continue uninterrupted between battles.

For the various character specific stat buffs that are intrinsic to their kit (damage, max health, protection, mastery etc):

This is way too broad of a category but a few good examples are the Basic Attack mechanics for Stranger, Luthen and JML that cause speed and max health, respectively, to stack on continuous use (up to some maximum), and then you have the special abilities for LV & JMK where the use of their special ability increases the damage of the attack (to some maximum) -- so on and so forth (this list is endless)

For GL Ultimates: I also have a question about GLs ultimates in the same setting - if you finish the first battle with SLKR, Rey ultimates still active - you begin the second battle with them still active but if I noticed correctly, JMK & LV ultimates do not follow the same pattern, you don't begin the second battle with the buffs active and the ultimate charge begins at 0           -> (correct me if I'm wrong here, it happened long ago and since then I never activate those ultimates in the first battle because of that experience)

Mechanic oriented debuffs seem to follow the same rule pattern: the continue on your character between battles (ROTE LS "no confidence" debuff for example) but Armor Shred debuff does not carry over.

Is there any rule to these mechanics? This seems unnecessarily complicated and honestly it seems not alot of thought has been put into this - does anyone know how this works?

Thanks in advance!

EDIT: I forgot to mention Jedi Vanguards JMMW and investigation stacking - have you noticed in the raid for example that if Disguised Clone Trooper is counter attacked before he enters stealth when no enemy has an Investigation stack, he gets a stack, enters stealth and you can't do anything? :D if he gets Dazed and is forever in stealth you are unable to apply Investigation to any other target in the meantime, this is actually quite hilarious
