Viper Napuatzi fight could be better (possible spoilers for fight)

Hi. So I'm about 2 days and 6 hours into the game and so far there's only one boss in the game that has pissed me off and killed me more than 2 times (closer to 10 actually). That's Viper. While I think the concept and design of the fight is fun and interesting, there are at least 3 issues with the fight that made me hate it.

1 - When the legion starts attacking with spears, the attacks are hard to dodge. I found three reasons - first, the boss shoots fast-moving projectiles that look dangerous and distract you, second, the highlighting of the legionnaires before the attack is not good enough to quickly notice the attack and react to it, and third, there are no indicators of how wide and long the attack area will be
2 - Right after the legion spear attacks, the boss will sometimes start doing an instant poison barrage attack. The window between the end of the legion attack and the poison barrage is so small that if you dodged the spear attack at the edge of the arena, you could get hit by the poison attack at the end of the dodgeroll, get stunlocked and die. I think the window after the spear attack should be a little bigger or the boss shouldn't be able to do a poison barrage attack right after it.
3 - During the meteors attack, danger zones from smaller meteors in the first part of the attack gets covered by ice terrain making it impossible to see(and, as a consequence, evade) them. This, however, doesn't happens during the second part of this attack, which makes me believe that it is more of a bug that intended feature of that fight, but i will still put it here

Point 3 is totally legit

Other than that though I felt this boss had by far the best telegraphing and fairest timings of the "the arena is also a monster" fights.

In addition to the list. After the phase with meteorites, the boss may end up behind the formation of warriors if at the end of the phase he is at the edge of the arena covered with an ice wall. After the second phase with spears, the probability is close to 100% due to the size of the arena. This leads to the inability to deal damage and end the battle; I had to roll back to the checkpoint through the menu about 8 times
