You keep saying this but you're actually wrong.
6e was a tremendous nerf.
The units that got cheaper generally got WORSE, be it rules changes on scything talons, or instinctive behavior changes
The minor points drops do not make up for these massive loses, like not longer getting re-rolls with 2 scything talons or, re-rolls on 1s with basic talons
The army does not have the same performance because the Tyranid Psychic powers are greatly weakened compared to you know, Biomancy. Its not horrid, but Biomancy in general was far stronger than the tyranid hive mind powers and almost every power was useful in some way. The tyranid hive mind powers are generally weaker.
The changes to IB ARE NOT greatly overblown, before a unit with feed would start charging 100% of the time, now it does it 50%, and the other 50% its EATING ITSELF, the lurk units are significantly worse as well, because instead of holding objectives your termagants have a 50% chance to go running off the board like retards.
The tyranids are worse in every single way, our strong units like hive guards and Tervigons took significant nerfs to their functionality, and while there were minor buffs to the Mawloc and the Flyrants, they aren't that significant, the flyrant was already auto-include.
The only changes that are buffs are the addition of the crone, new shadows, and the MASSIVE points decrease of the Tyrannofex to make it takeable.
Nothing else was good enough for a serious mention.
Incontrol placed 12th, and 6e in the hands of blackmore placed 26th. Thats proof of loss of power
You really need to stop spouting this bullshit in every thread, it is entirely fallacious, we lost performance across the board, and the minor points decreases do not make up for how insanely crippling IB is now, nor do they make up the loss of Biomancy, Telekinesis, and Telepathy, all those fields gave much more utility to the nids, hell, the Telepathy Primaris scream is better than our rolled for scream.
