Learn to read too. In the PS3 maybe you can't see a boss with just 100-150 players hitting it. In the PC/PS4 maybe you'd probably need well over 700-1000. How does that even compare?
Look I've been on both platforms, on PS3 and PS4 (can you say the same?), so I can state FACTS, and FACT is something is UNPLAYABLE on the PS3 when a lot of people gather in on point to hit something. Hell I wasn't even able to see like 95% of the people gathered in Mor Dhona when I was playing on my PS3, and when I upgraded to PS4 the entire place was FLOODED with people.
Again, don't even open your mouth if you haven't even tried the PS3 version.
