Well first of all, remember that the health regeneration buff is only on maps with a predator in them. Secondly, sure it is the most powerful buff for the monster, he in return gets a crap perk from the Mega-Mouth: Increased pounce damage. Wheras the hunters gain 50% cooldown reduction on class-based abilities (personal shield, mobile arena etc) and is probably one of the best buffs for the hunters. And third, it can be countered by the hunters by killing the predator that holds the perk. And last, it’s only good if you’ve actually taken damage. If not, the perk is useless.
Now, you can argue that it creates un-counterable to play to a hunter team that defends the generator. However, you have to imagine this situation to realise that it doesn’t even matter that much:
Say the game has been going on without any real engagement. The monster still has full health, no strikes on the hunters. The monster reaches stage 3, the hunters go to the generator. As a monster, all you have to do is go to the hunters, take down the trapper/medic (medic first if it’s Lazarus ofc) and leave. Then, armor up and engage again. Take down the medic/trapper again, retreat, gain armor, re-engage. Most of the time, the hunter’s wont get through your armor if you completly focus on just getting one strike and then retreat.
I’ve thought a lot about what the monster can do vs a team that doesn’t even hunt him and just sits by the generator. Well that’s very simple: Evolve to stage 3, get full armor, a nice buff and engage. Get a strike on the trapper/medic, retreat and gain armor. Once you’ve got full armor again, re-enage and get another strike. Retreat, gain new armor and re-engage.
Very boring, but it works vs a team that doesn’t hunt you.
Oh and don’t worry about the in-game timer. It’s 20 minutes, more than enough time to retreat,armor up and re-engage a couple of times.
