Combat, Biotics, or Tech == In which tree will you put more points?

Combat and Tech. Going for an Infiltrator build focused on Sniper Rifles and Assault Rifles. I'll probably take Cloak, Incinerate, and Overload.

Well, devs said that you can grind out all the skills in a single playthrough, so I guess it doesn't really matter.
But I guess mostly tech since everyone and their mothers have biotics and combat skills are quite boring on the surface.

I just wanna make a highly mobile Biotic soldier. With different profiles for different distances to enemies.

I just need to know the cooldown of every skill to say something reasonable. This matters, due to the favorites stuff and everything going on cooldown.

That's already my plan for my Sara play through (second). Cloak for DPS/Survivability, Overload for shields and Incinerate for armour sounds like the perfect combination to me, especially as it appears that both Incinerate and Overload can be specced to both prime and detonate so you'd get fire and tech combo's too.

That said, it's absolutely undoubted that my first play through will focus heavily on Biotics because Charge. Well Biotics and Combat for weapon skills/passives.

Charge, Nova and Annihilation looks too delicious to pass up. I'm waiting to see what the Vanguard profile bonuses are before choosing between it or Adept

We know we can at least go to level 70 with 5 point per level => 350 point. One ability max cost 21 points so having 350/21 = 16 maxed ability which is more than enough. Now what I want to know is the progression for profile. We know there are 6 level of profiles
Rank 1 : ?
Rank 2 : 24 => level 5
Rank 3 : 58 => level 12
Rank 4 : around 100 => level 20
Rank 5 : 156 => level 32
Rank 6 : ? (200 ?) => level 40+/-
Divide by 3 for the explorer profile and I guess by 2 for hybrids profiles. Being Rank 6 in two exclusive profiles seems impossible if max level is 70.
Hope this help for planification.

Now for my part. Biotic I neglected in the past seems to be way more interesting than before with a ton of cool effect, movements/shields/CC/area effect but poor damage ratio so I might emphasize on it. However I like to play on harder difficulties but don't like the bullet sponge opponents that comes with it. So I will invest a lot of point in soldier passives (and because other spec abilities are more fun) for overall effectivness and a select profile for tougher enemies. I like the explorer profile so I will start investing everywhere right at the beginning.
Tech seems no that good, I don't find summoning turret and drone fun so i will invest point in it to unlock hybrid profile and get useful abilities like overcharge, tactical cloak, the team passive and shield passive and max them out.
Profile 1 : Adept => Aoe and fun abilies for opening the combat
Profile 2 : Soldier => Turbocharge, tactical cloak anti-armor kind of stuff, burst damage for tougher opponents
Profile 3 : Vanguard => Charge, Backlash, Cryobeam Close combat biotic option.
Profile 4 : Explorer => Overcharge and other situational abilities as an alternative opponer to Adept.
With a Combat gear probably.
Profile 5 : Infiltrator, with the huge bonus to sniper rifle (+70% damage +30%accuracy and stability at level 3) it seems the only way to bother taking a sniper as they slow your cooldown when changing profiles... but I don't expect to go beyond 50 point invested in tech, maybe in another playthrough.

So a ratio Biotic/Combat/Tech like 1/1/1 at the start of the game to unlock most of the ability i want to play it then 1,5/1/0,5 for optimization. That should allow me to unlock at least Explorer 5, Vanguard 5 and Adept 5 or Soldier 5. I'm not sure biotic is the most intersting spec to optimize for damage.

See if I can create some of the unique classes from ME3 Multiplayer like the N7 Shadow or Demolisher.

Tech and Combat, as I said before in another thread I feel biotics are too convenient for the protagonist of the story to have. Same goes with Magic in fantasy games. I like my main/canon characters to be more grounded for me, as the viewer of the story, to relate more with the protagonist.

I'm going to focus primarily on the vanguard build, but I'm definitely going to do more tech stuff this time.

At first I was planning of going full biotic because Charge + Nova and Pull+throw looks awesome, but then I really love sniping things too, so I'm starting to think that Tech/Combat might be what I'm going to go for.
