My Thoughts for Achievements

Instead of no rally points like on cea, make rally points. Also:

Let’s say there is a mission called cortana. Here is how achievements would go. Normally, 40G. Here:

To reach RPA: 10G Breaking through
To reach RPB: 10G Reunion Tour
To reach end: 20G Wake me, when you need me

This will give the player a feeling of lots of levels, rather than only 9-10.

My achievement ideas other than levels:

5G Well you kinda suck: Campaign easy
125G The one and only: Campaign normal
150G Guest appearance: Campaign heroic
200G Galaxy renowned: Campaign legendary
50G Universally recognised: Campaign legendary alone
1G +1: Unlock every achievement
343G Specially selected: Feature on any of:

Waypoint
Fails of the weak
HaloWaypoint (YouTube)
Gamefails

Some very good ideas, I don’t need to comment on them. Well, there is one that needs commenting on. The last one.
I think it would be too much of a challenge to achieve, considering that only the minority of people have ever been featured on any of these things. It may frustrate some people, due to the difficult task at hand… And I know how annoying it is having a few achievements left to get, that really are just ridiculously hard to get!

I personally hate 1G achievements or just unevenly numbered achievements, in general
