First: I think we should be able to explore enemy faction's territories...
Okay you're starting to sound like one of those that just wants to gank lowbies.
Second: Stat scalling on cyrodiil is extremely bad... Weak and strong players exist at any MMO, and if the weak wants to do a good job on a war, they should train harder.
Okay... now you're really starting to sound like you want to gank lowbies.
Third: I think max level 50 is a quite low, and leveling is one of the major features on a MMORPG.
LotRo, and swtor started at level 50. That's where expansions come in, and there's bound to be new levels added with it... 50/60 is the standard for MMOs.. I don't know why you want it to be such a grind. Let them come out with good content and quests rather than doing quick sloppy grindfests for end levels.
Fourth: Many will disagree here, but I think ESO should be an open world pvp game... Open world pvp is extremely exciting and thrilling, and will help to immerse the player in the world.
These poor low levels.. they will never meet the knife you so willing want to shove into their backs.
Do you know how large Cyrodiil is? It's massive.. you won't even think about open world pvp once you get in there and see for yourself. There's still going to be a huge thrill of unexpectedly finding new enemies just because the size of the territory will prevent you from meeting someone every two seconds, even with 2000 people in it. If you want to see other territories that aren't in your faction, you can always make characters in other factions. I'm an altoholic and will be for sure making at least 1 in each.
