I'm really happy the IG tanks are so hardcore. I think its the way it should be.
The infantry are just too elite. The orders, regimental doctrines, theimmune to morale and just the spammability and strategms are just way to over the top. Space Marines, Primaris Marines etc. are nowhere near this elite, versatile in all the tricks they can pull and that makes no sense.
Especialy when it comes to Conscripts these problem also got worse. With shooting at full BS on overwatch, and firing into combat, ressurecting them for command points, joining smaller units into bigger units... its like they doubled down on the power of the conscripts.
I played a maelstrom game against a 200 Conscript list a few weeks ago and my opponent just had an infinite amount of bodies across 6 ft of board and by turn 3 holding 3/4 of the objectives and there was nothing I could do to stop him.
The other problem is edition-wide: the only effective anti-horde out there is another horde. The giant nerf to blast weapons is a wonderful gift to every AM Commander and Ork Warboss--there just aren't enough bullets anymore.
This is exactly the issue. The firepower of the big blasters is nowhere near up to the task. The old Fire Prism, Frag Missile Devs, Exocrine, Thunderfires etc would have been all stars in this edition if it could clip as many dudes as it used to. Then -even though I think they are still too elite with orders + doctrines- I wouldn't care one bit because at least you have a solid tools to take them out. With the nastiness of IG tanks you'd have to protect these anti-horde assets but at least you'd have the tools.
I think this has been the first BIG mistake of 8th edition.
