Hero Experience Bars

I noticed that it can be tricky to know exactly how much experience your heroes need before attaining certain levels. It would be nice to have some sort of experience bar for them, maybe replacing your own experience bar with theirs temporarily while they are up on the Inventory screen. Even something as simple as pinging the avatar on the hero pane, I noticed that you can ping their skills and health as well.

Why are there several threads with posts asking to see a hero's xp bar? Hmm... I haven't even thought about a hero's current xp, much less want to see a bar. Is it so important to know exactly when a hero will level up?

Principle reason, if you're bringing a level 20 over from Cantha or Tyria, you have to grind all of your heroes up to level 20 (especially Koss, who starts at level *3*). After they reach level 20 I couldn't care less. But until then it would just be convenient.

Don't really see the point of this. If Koss is lvl5 and 5% to the next lvl, he still lvl5. If Koss is lvl5 and 95% to the next lvl, he still lvl5.

Off topic:
If you have prophecies, just take them to Witman's Folly and buy a 5 minute 250% xp scroll. There's 4-6 bosses out there that will renew your scroll. I've seen Koss go from lvl2 to lvl7 in one run. I usually run with two heroes I'm lvling, Olias has a MM, and Alesia for a bit of healing.

I know that being able to see what percent they are to the next level doesn't accually help them level, but if you think of it like that, then why can we see the amount of XP we have before we get to lvl 20? Why did ArenaNet put that in if it's that useless? It's because it's nice to know how far they are from leveling. It makes you feel like you are accually getting somewhere as far as leveling them, excluding when they accually level.
