The Best Way Of Making These pet's not over-powered from what others have said are:
- 1.Nerfing stun's completely on bosses only. (So they no longer work on bosses relevantly)
- 2.Reduce the chances of stun/CC on bosses or Players/mobs. (not have a complete 100% chance to stun or CC and have a LOW chance rather than a HIGH one.)
- 3.Add More Cool down Time?
- 4. OR Have a Reflection Option From the pets attacks. (for example, if stun/cc attempts to hit a boss, a boss can reflect the stun/cc on the player who brang out the pet, (Boss skill reflect) OR Stun/CC reflecting armor (chance) )
Option 2 could be better.
2 - say there's a lower CC chance ---> get more people to stun/CC (2-3 at a time?)
3 - say there's more cooldown --> get more people with stun pets
4 - say I cast a stun pet, and I get stunned myself completely, what about my other 9 raid members?
Remember, you only need 2 people with the current system to completely bug a boss. Do NOT make changes so that the only difference is that instead of 2 people with pet stuns, you need 7-8. It's the same all over again. I'd recommend getting it right the first time and adding complete immunities. Several months down the road, everyone will have 60-80%++ completion, and it'll become common all over again.
Regardless whether the immunities are temporary or permanent, the important part is that the bosses must be immune to stun/CC for a reasonable amount of time (and reasonable intervals). You can choose complete immunity or choose a temporary ~10s immunity, both are fine but the immunity needs to be there. Not misses, not cooldowns, those are all solvable by just getting more people with these pets.
Both approaches are fine. The problem is, we have experience with kRO2 Devs, and the bugs they introduce, and the amount of time it takes to fix bugs, and their attitude towards exploits.
Do we want them to implement a "complicated temporary immunity" or a "complicated cooldown" pet system which has potential for exploits/bugs? Remember - we're talking about RO2, a game that hasn't been so ... bug-free in the past.
I feel like there is only one chance where they will put so much time and effort into fixing the pet system, and that chance is now. If they add something which can possibly be exploited once again in the future, you can expect it not to get worked on again for a very long time.
That's why I'd argue that it's better to take the safe and simple way out, and add complete immunities.
