I've already come to terms with being an MMO tourist(it's a shameful fact the old gamer in me isn't proud of), usually I can take a character to lv40 before the repetition kicks in and I uninstall.
Now I wouldn't mind grinding quests to lv50, then turning fully to PvP. But in ESO, you quest your way to lv50... and it all begins again. Then you need to grind quests from Veteran Rank 1, up to VR10, which is about the same time as lv1-50 all over.
With my modest gaming time, it'll take me 2 months to lv50, 4 months to VR10. But it's not over. The bar will be raised to VR12 and the grinding resumes, from lv1-50.. all over.
If I made it to VR12 in 6 months, VR15 will be out by then and so on and on. The fact you'll need to be at the highest rank to access the newest PvE content is where the game lost its appeal.
The quest grind wouldn't be so bad if there was more combat and less running around. There's no point to reading the quest dialogue as the game forces you to follow the arrows around. One quest sends you to search for a suspicious cultist at the city gates. The actual quest marker leads you into a nearby house and down into the hidden basement. So how do you progress from searching the crowds(as the dialogue suggests), to snooping around houses and searching their basements.
The dialogue is redundant, the game forces you to ignore NPCs and just follow the arrows back and forth. I could endure it to lv50... it's when I see VR10, then VR12, then VR15 in the distance that I know I won't experience it to the end.
