Didn't u both forget that you re speaking of a single t1 mod?
Please re-read your sayings.
You speak about the strongest and most useful while creeping t1 mod in the game using tips like: "you just need to know when to strike" or "look there is one unit in the game who can mass debuff!"
"Guys how do I counter Purification mod?" "You just need to know when to strike. Use scan: catalogue!"
"Most battles are won in 3 tirns but here we get only 2 tirns of 30% all damage and status chance reduction by a t1 mod, it is not that strong, why don't you get it?"
" Who told you this mod makes you unbreakable while creeping? My units die with same frequency w-w/o it!"
If you wish to fire units at enemy units and forget, I recommend playing different game. Clearly this game isn't for you. Civ5 is much more simpler. Units in there is just base strength vs base strength and then modified by abilites gained by leveling and terrain bonuses and surplus/deficit of resources / happinesses.
Nanite injectors is basically just an small heal at most it helps anyone who gains a vanguard colony and influence them to join them then they too can unlock nanite injectors. Gain a bonus in creeping. Shake off the damage of a single hit.
Many many troopers has died without getting to use their nanite injectors.
Reasons:
1) They got shot at by a strong ranged weapon.
2) They got caught in melee.
3) Misclicked which results in accidently telling a trooper to charge to his death deep into middle of enemy group when I intended to shoot instead. Whoops.
4) Focus Fire.
5) They got critted hard.
6) A hero noticed them and now they're fleeing for their dear lives.
7) They got mind controlled and is now operating for the enemy using the nanite injectors against you.
8) Six of your godly troopers with nanite injectors ready to go just fired at a group of indentured slaves and didn't notice they had static field equipped whoops, now they're all stunned. Then killed by indentured on syndicate's turn. Drat. What a horrific miscalculation.
9) All those Vanguard AIs who bring troopers equipped with nanite destroyers of worlds injectors has been laid low and defeated by me. Not a single one of them could stop me.
10) My Big Brain needs to be nerfed for the AI to stand a chance so they can let nanite injectors carry them to victory.
11) You're unable to accept that age of wonders' manual battle is very awesome and has so many different factors that could change the way a battle could go.
12) There will be always something good, should nanite injectors get nerfed. Purification Field is next.
13) Now that Horrible purification field is nerfed. Finally! Now we can move onto next balance issue.... Fire ammo. its too strong against the growth.
14) Fire Ammo is now nerfed and the growth gets healed every time they get burnt. Finally!
15) AoW is now another mediocre arena death match game that I uninstall from my pc and I go play PSO2 that's coming out in few days as the result of fantastic kneejerk nerfs that's based on gut feeling instead of actual empirical data as battles play out between all factions and their secret techs and nanite injector is only doing it's job of keeping troops earlygame having hp. How dare it do is job, nerf it.
16) Fun Fact, I don't play civ series anymore. Me and Firaxis has divorced after the thing they call Civ6 and their sad tiny as their citizens cry out for my large prosperous happy cities in aow maps.
tl;dr AOW series is fun. Silly nerfs based on gut feeling reduces the fun.
There is plenty of counters to nanite injectors. You just have to use your big brain. There's too many to list and i'd have to write a freaking essay. That's just for the nanite injectors alone. If you don't want to, there's another option, world of warcraft and participate in the pvp there instead. Slap on as much resilience and stats you can and go fight.
