Chaos magic. Is it necessary?

Chaos isn't critical for the Ranger, of course, but there are still very powerful options. For example, Armageddon with the Fire Lord and protection against it in Light. With an elf's spell power, the damage won't be very high, but the enemy army will lose half of its armor for an entire turn, which, with the Union's troops' initiative, will lead to huge losses in the enemy ranks.
Or simply enchant Rain with Fireballs.
And if you fully utilize the ability of the new Druids, you can get more spell power than a Warlock, and with that spell power, it's best to cast Freeze on an arrow.
So, Chaos shouldn't be ruled out.
