Ozy doesn’t have the damage or protection (or other features) necessary to make up for a lack of healing. When flown right, Morak is hard to touch and can one shot towers over and over.
Morak definitely should not have receive any ability to heal, as that dragon goes down as one of the much more powerful legendaries. Ozy is not of the same caliber as Morak, so while it is a good thing Morak wasn’t given the ability to heal, Ozy is just crippled.
Ozy has 1) a spell similar to Hyaku’s meteor (so not amazing). It’s a short duration tower freeze and damage spell that ignores mages but costs a full 2 rage (not that it should cost 1 rage, but compared to other 2 rage freeze spells it’s a tad underwhelming) it’s not a bad spell, but for Hyaku it wasn’t sufficient for that to be its only spell with a damage output. Hence Hyaku being a quite crappy drag 2) a shield that applies rage marks. This is a quite good spell: 1 rage, white, decent duration, and rage marks; but if there’s a Howi or ice flak…which most bases have…yeah. 3) a spell with a pretty ok damage output but has the disadvantages that come with randomized damage assignment. Sometimes it’ll just hit one tower and then blast into a monument and stop. 4) a dark flak resist. Ozy is basically a Hyaku that traded the ability to heal for more damage.
Compared with Morak
1)Basic attack is tower removal. 2) a 0 rage temporary damage prevention (can be disabled by ice flaks or howis, but it doesn’t rely on this spell for rage like Ozy does) 3) a cloak that instantly regens its tower removal and as a cloak allows it to avoid damage. 4) a cloak that increases its rage generation and allows it to attack while not getting attacked.
