World-of-warcraft – Merge Starter and Standard Edition

No

Once you account status goes to "Frozen" (expired) you can't go pass the main menu so it doesn't matter if you are under lvl 20 when you cant select that particular character.

What you can do is have 2 WoW accounts (not Battle.net accounts), one is "frozen" and the other is "starter", you will need to create new characters but its purpose is to check updates and chat with people. When you subscribe (unfreeze your main account) the other one will remain "starter".

Now what I don't know is how to add more wow accounts... I have 7 of them name WOW1, WOW2... The problem is I was adding them when it was 10day trial and you had button in Battle.net account "add 10d trial" any you could click it anytime. Try to find something like that.

You could also register another WoW account with different username and pass and then merge use the merge option on your main account.

They won't delete your characters -_- after you lose your starter edition when your days expire your account gets freezed and you can't log in until you pay again.

You can buy battlechest if it is cheaper in your region...but you activate one by one as you play.I would buy one by one since old expansions get cheaper and cheaper with every expansion they release,and if you get bored in middle you can quit without spending money on all expansions.

1. You play until lvl 25 (Free)
2. Use WoW trial 10 day (should be on Battlenet page)
3. Buy WoW original (you get 30 days with it)
4. Buy 60 days key to get lvl 60 (if not already)
5. Use Burning crusade 10 day trial (should be on Battlenet page)
6. Buy Burning Crusade + 60 days
7. Use WoTLK 10 day trial (should be on Battlenet page)
8. Buy WoTLK + 60 days
9. Cataclysm 10 day trial (should be on Battlenet page)
10. Cataclysm + 60 days ...

Use your 10 day trials when you reach max level,before that use 60 day keys as needed.
