Level Limitation

How does the level-to-limit ratio work when it comes to item drops? On the starting maps, I don’t receive any experience or gold for defeating NPCs, whereas on higher-level maps everything works as normal. I can’t find any threads on the forum that discuss this. It would be great if someone could put a table showing the level range for drop on specific maps.
I’m asking mainly because I’m currently farming on Map 7, where I still get drops, but on Map 6 I don’t.

 

Hi
It makes sense, the higher your level is, the more small cards you lose. To avoid this, you need to join a guild and always use a level 50 guild letter.
Only 50s, no 100s, 150s or 200s. The 50 guild letter only lasts 30 minutes; to reactivate a new one, you can play an arena match or a map duel. I’d recommend a map duel with another player, because after the first duel, whether you win or lose, you can activate a level 50 guild letter, then play another duel and reactivate a level 50 guild letter; that way, you’ll have 1 hour instead of 30 minutes.
The advantage of the 50 letters is that they slow down your level progression, because, contrary to what 80 per cent of new players think, your level has nothing to do with your power.
The longer you stay at a ‘low level’, the more gold, diamonds and items you’ll be able to accumulate, and the more you’ll be able to complete the tavern quests on the small maps, the achievements for Chests 1 and 2, and the Kirus, Lodos and Sobeck chests (especially the monsters), etc.
With this tactic, you’ll reap a triple benefit from the maps, quests and achievements, as well as the chests from monsters and npc, you’ll be able to unlock the workshop and, most importantly, and this is vital, tackle the colossus on maps 8b and 9b, which will earn you plenty of diamonds, gold and rare items every day.
Once you reach level 36, you’ll lose all maps from 1 to 12.

I'm currently level 29. My damage is ~1500 using stone, and each of my 100 guns is tier 4. Is the only way to get better is to wait for the event auction and constantly upgrade my guns? Moreover I've noticed that I'm currently unable to find any opponents on the battlefields, I suspect that few players at my level are participating in the event, if anyone is even signing up for the queue... I haven't been able to obtain even a single Eagle medal. I suspect the same will be true for Bhutu, Kirus, etc.
