Are you DPS or Tank? Your answer will either validate or disprove your claims.
Even as DPS Ive seen this in certian instances. Going up against two strongs and two trash mobs I found myself overwhelmed. While I understand theres a need for it to be a challenge to a Tank with the same storyline. I didnt choose DPS to fall flat on my face every couple of fights due to finding myself in situations (which I cant help) that involve tanking.
