Does anybody have any ideas for mythic REQs or any REQs in general?
Yes. 2 in fact, and they are so powerful that they would be too crazy for Warzone.
#1

BoltRifle
A sniper with High Explosive Armor Destroying rounds with a railgun barrel. Its Scope can cycle between 4x 9x 24x and 49x zoom. It causes a small anti grav explosion upon impact, and can 1 shot the toughest of Pelicans and Phantoms

A Grav hammer infused with Forrunner tech capable of sending ‘Splinter Waves’

I love sniping so I came up with Mythic versions for the 3 snipers (Another sniper Rifle - I also didn’t include the Halo 2 Beam) They may be a little OP but ah well, let your imagination run wild and that. Have not come up with req levels for them yet.

Shrouded Arrow
Description:
The UNSC continues to pump research into the art of killing without being seen. Mythic sniper rifle that provides the user with active camouflage, a larger ammo pool and an on-scope motion tracker. Shoots armour piercing rounds that are capable of killing any Spartan regardless of the impact location - even over shielded enemies. The armour piercing rounds are capable of doing usual sniper damage to enemies in armoured vehicles (such as the wraith), but the weapon is not especially effective against the vehicle itself. (What I mean by this is that, if you shot a wraith cockpit and the bullet would hit the pilot in the head, it would be a ‘sniper rifle headshot’ and they would die instantly - obviously if they were hit in the body, their shields would go down)

Desolating Harvest
Description:
Towards the end of the Flood-Forerunner war, master engineers needed a way to provide ground soldiers with ammo to last them out for long engagements. Mythic binary rifle that provides the user with active camouflage, an over shield and a visible motion tracker when scoping. The rifle absorbs the energy of its victims, replacing the shot when a kill is evaporated; for this reason it does not have an increased ammo capacity. However, the rifle is extremely effective against vehicles, doing massive damage - but when a vehicle kill is achieved it is unlikely that the victim will be evaporated so ammo is lost.

Lightening of the Worthy
Description:
Sangheili war tacticians wanted a way to achieve more kills more quickly from distance. The was the result. Mythic beam rifle with increased energy capacity, a visible motion tracker when scoping and an over shield. The shots from this sniper are powerful enough to kill Spartans from any impact location - but a headshot is needed to kill enemies with an over shield. Upon impact, excess energy jumps from the target to a nearby enemy, downing their shields or killing them if their shields are already down. Smart targeting means that, if there is a choice between an extra enemy with a shield and one without, the rifle will kill the one without, as to save ammunition. Used against vehicles an EMP is released on impact but actual damage is small
Wooo! That took a while to type 
Echoes of the Old
Older secrets unlocked by cunning Sangheili were lost in the splinter of the Covenant and the Swords of Sanghelios. Advanced Beam Rifle with increaded battery capacity and snapshot accuracy, that creates a series of rippling plasmatic explosions when fired against heavy armor.
Nice
