A troll post? I just joined ZAM. This is what I'm talking about. People blindly posting about other people's posts. Forums were built for discussion.
Maybe one of these replies have already changed my perception of continuing. Seriously though, some of you should grow up and not just bash people for opinions.
This is why children shouldn't be allowed to join forums. Next time some of you decide to reply to a post, learn to give advice or recommend things or suggest things and not simply blast someone for their opinion.
First off, it was a bit rude for people to assume this was a troll post... however, as pretty much everyone else has said, you leveled 2 classes to 15. You didn't even attempt a single dungeon yet (which IS the group content). You didn't fight Ifrit, you didn't join a grand company, you didn't get your chocobo, you didn't unlock any jobs, I'm guessing you haven't crafted, gathered, or explored all that much. The game has a million things to do. If you actually give it a chance, and level past 15, you'll be fine.
Secondly, there is PLENTY of challenge in the game. Some of the later dungeons are quite difficult, the Titan and Garuda fights offer an excellent challenge, and endgame content looks to be pretty beastly. What did you expect to get from a post like this? Sunshine and happiness and people giving you a pat on the back? You tried almost none of the game, and made baseless accusations about difficulty. If you had expected different responses, you should have worded your OP much differently... such as, does the challenge ramp up at higher levels? Instead of just assuming everything is easy. Nothing annoys people more than when others make blanket statements about something they really don't understand and haven't even attempted.
